-implies <tt>!(x &lt; z) &amp;&amp; !(z &lt; x)</tt>), then it satisfies the mathematical
-definition of an equivalence relation.  In this case, <tt>operator&lt;</tt>
-is a <i>strict weak ordering</i>.
-<P>
-If <tt>operator&lt;</tt> is a strict weak ordering, and if each equivalence class

-Only <tt>operator&lt;</tt> is fundamental; the other inequality operators
-are essentially syntactic sugar.
-<P><A name="2">[2]</A>
-Antisymmetry is a theorem, not an axiom: it follows from
-irreflexivity and transitivity.
-<P><A name="3">[3]</A>
-Because of irreflexivity and transitivity, <tt>operator&lt;</tt> always
-satisfies the definition of a <i>partial ordering</i>.  The definition of
-a <i>strict weak ordering</i> is stricter, and the definition of a
-<i>total ordering</i> is stricter still.

-Multi-Pass Input Iterator
-</H2>
-
-This concept is a refinement of <a
-href="http://www.sgi.com/tech/stl/InputIterator.html">Input Iterator</a>,
-adding the requirements that the iterator can be used to make multiple
-passes through a range, and that if <TT>it1 == it2</TT> and
-<TT>it1</TT> is dereferenceable then <TT>++it1 == ++it2</TT>. The
-Multi-Pass Input Iterator is very similar to the <a
-href="http://www.sgi.com/tech/stl/ForwardIterator.hmtl">Forward Iterator</a>. The
-only difference is that a <a
-href="http://www.sgi.com/tech/stl/ForwardIterator.hmtl">Forward Iterator</a>
-requires the <TT>reference</TT> type to be <TT>value_type&amp;</TT>, whereas
-MultiPassInputIterator is like <a
-href="http://www.sgi.com/tech/stl/InputIterator.html">Input Iterator</a>
-in that the <TT>reference</TT> type merely has to be convertible to
-<TT>value_type</TT>.
-
-
-<h3>Design Notes</h3>
-
-comments by Valentin Bonnard:
-
-<p> I think that introducing Multi-Pass Input Iterator isn't the right
-solution. Do you also want to define Multi-Pass Bidirectionnal Iterator
-and Multi-Pass Random Access Iterator ? I don't, definitly. It only
-confuses the issue. The problem lies into the existing hierarchy of
-iterators, which mixes movabillity, modifiabillity and lvalue-ness,
-and these are clearly independant.
-
-<p> The terms Forward, Bidirectionnal and Random Access are about
-movabillity and shouldn't be used to mean anything else.  In a
-completly orthogonal way, iterators can be immutable, mutable, or
-neither.  Lvalueness of iterators is also orthogonal with
-immutabillity.  With these clean concepts, your Multi-Pass Input Iterator
-is just called a Forward Iterator.
-
-<p>                
-Other translations are:<br>
-std::Forward Iterator -> ForwardIterator & Lvalue Iterator<br>
-std::Bidirectionnal Iterator -> Bidirectionnal Iterator & Lvalue Iterator<br>
-std::Random Access Iterator -> Random Access Iterator & Lvalue Iterator<br>
-
-<p>
-Note that in practice the only operation not allowed on my 
-Forward Iterator which is allowed on std::Forward Iterator is 
-<tt>&*it</tt>. I think that <tt>&*</tt> is rarely needed in generic code.
-
-<p>
-reply by Jeremy Siek:
-
-<p>
-The above analysis by Valentin is right on. Of course, there is
-the problem with backward compatibility. The current STL implementations
-are based on the old definition of Forward Iterator. The right course
-of action is to get Forward Iterator, etc. changed in the C++ standard.
-Once that is done we can drop Multi-Pass Input Iterator.

+
+Boost.Utility, part of collection of the [Boost C++ Libraries](https://github.com/boostorg), provides a number of smaller components, too small to be called libraries in their own right. See the documentation for the list of components.
+
+### Directories
+
+* **doc** - Documentation sources
+* **include** - Interface headers of Boost.Utility
+* **test** - Boost.Utility unit tests
+
+### More information
+
+* [Documentation](https://boost.org/libs/utility)
+* [Report bugs](https://github.com/boostorg/utility/issues/new). Be sure to mention Boost version, Boost.Utility component, platform and compiler you're using. A small compilable code sample to reproduce the problem is always good as well.
+* Submit your patches as pull requests against **develop** branch. Note that by submitting patches you agree to license your modifications under the [Boost Software License, Version 1.0](https://www.boost.org/LICENSE_1_0.txt).

-<p>The template class call_traits&lt;T&gt; encapsulates the
-&quot;best&quot; method to pass a parameter of some type T to or

-as in the table below. The purpose of call_traits is to ensure
-that problems like &quot;<a href="#refs">references to references</a>&quot;
-never occur, and that parameters are passed in the most efficient
-manner possible (see <a href="#examples">examples</a>). In each
-case if your existing practice is to use the type defined on the
-left, then replace it with the call_traits defined type on the
-right. </p>
-
-<p>Note that for compilers that do not support either partial
-specialization or member templates, no benefit will occur from
-using call_traits: the call_traits defined types will always be
-the same as the existing practice in this case. In addition if
-only member templates and not partial template specialisation is
-support by the compiler (for example Visual C++ 6) then
-call_traits can not be used with array types (although it can be
-used to solve the reference to reference problem).</p>

-<p>Notes:</p>
-
-<ol>
-    <li>If T is already reference type, then call_traits is
-        defined such that <a href="#refs">references to
-        references</a> do not occur (requires partial
-        specialization).</li>
-    <li>If T is an array type, then call_traits defines <code>value_type</code>
-        as a &quot;constant pointer to type&quot; rather than an
-        &quot;array of type&quot; (requires partial
-        specialization). Note that if you are using value_type as
-        a stored value then this will result in storing a &quot;constant
-        pointer to an array&quot; rather than the array itself.
-        This may or may not be a good thing depending upon what
-        you actually need (in other words take care!).</li>
-    <li>If T is a small built in type or a pointer, then <code>param_type</code>
-        is defined as <code>T const</code>, instead of <code>T
-        const&amp;</code>. This can improve the ability of the
-        compiler to optimize loops in the body of the function if
-        they depend upon the passed parameter, the semantics of
-        the passed parameter is otherwise unchanged (requires
-        partial specialization).</li>

-be copy-constructed from which other types, those entries marked

-<h4>Example 1:</h4>
-
-<p>The following class is a trivial class that stores some type T
-by value (see the <a href="call_traits_test.cpp">call_traits_test.cpp</a>
-file), the aim is to illustrate how each of the available
-call_traits typedefs may be used:</p>
-
-<pre>template &lt;class T&gt;
-struct contained
-{
-   // define our typedefs first, arrays are stored by value
-   // so value_type is not the same as result_type:
-   typedef typename boost::call_traits&lt;T&gt;::param_type       param_type;
-   typedef typename boost::call_traits&lt;T&gt;::reference        reference;
-   typedef typename boost::call_traits&lt;T&gt;::const_reference  const_reference;
-   typedef T                                                value_type;
-   typedef typename boost::call_traits&lt;T&gt;::value_type       result_type;
-
-   // stored value:
-   value_type v_;
-   
-   // constructors:
-   contained() {}
-   contained(param_type p) : v_(p){}
-   // return byval:
-   result_type value() { return v_; }
-   // return by_ref:
-   reference get() { return v_; }
-   const_reference const_get()const { return v_; }
-   // pass value:
-   void call(param_type p){}
-
-};</pre>
-
-<h4><a name="refs"></a>Example 2 (the reference to reference
-problem):</h4>
-
-<p>Consider the definition of std::binder1st:</p>
-
-<pre>template &lt;class Operation&gt; 
-class binder1st : 
-   public unary_function&lt;typename Operation::second_argument_type, typename Operation::result_type&gt; 
-{ 
-protected: 
-   Operation op; 
-   typename Operation::first_argument_type value; 
-public: 
-   binder1st(const Operation&amp; x, const typename Operation::first_argument_type&amp; y); 
-   typename Operation::result_type operator()(const typename Operation::second_argument_type&amp; x) const; 
-}; </pre>
-
-<p>Now consider what happens in the relatively common case that
-the functor takes its second argument as a reference, that
-implies that <code>Operation::second_argument_type</code> is a
-reference type, <code>operator()</code> will now end up taking a
-reference to a reference as an argument, and that is not
-currently legal. The solution here is to modify <code>operator()</code>
-to use call_traits:</p>
-
-<pre>typename Operation::result_type operator()(typename call_traits&lt;typename Operation::second_argument_type&gt;::param_type x) const;</pre>
-
-<p>Now in the case that <code>Operation::second_argument_type</code>
-is a reference type, the argument is passed as a reference, and
-the no &quot;reference to reference&quot; occurs.</p>
-
-<h4><a name="ex3"></a>Example 3 (the make_pair problem):</h4>
-
-<p>If we pass the name of an array as one (or both) arguments to <code>std::make_pair</code>,
-then template argument deduction deduces the passed parameter as
-&quot;const reference to array of T&quot;, this also applies to
-string literals (which are really array literals). Consequently
-instead of returning a pair of pointers, it tries to return a
-pair of arrays, and since an array type is not copy-constructible
-the code fails to compile. One solution is to explicitly cast the
-arguments to make_pair to pointers, but call_traits provides a
-better (i.e. automatic) solution (and one that works safely even
-in generic code where the cast might do the wrong thing):</p>
-
-<pre>template &lt;class T1, class T2&gt;
-std::pair&lt;
-   typename boost::call_traits&lt;T1&gt;::value_type, 
-   typename boost::call_traits&lt;T2&gt;::value_type&gt; 
-      make_pair(const T1&amp; t1, const T2&amp; t2)
-{
-   return std::pair&lt;
-      typename boost::call_traits&lt;T1&gt;::value_type, 
-      typename boost::call_traits&lt;T2&gt;::value_type&gt;(t1, t2);
-}</pre>
-
-<p>Here, the deduced argument types will be automatically
-degraded to pointers if the deduced types are arrays, similar
-situations occur in the standard binders and adapters: in
-principle in any function that &quot;wraps&quot; a temporary
-whose type is deduced. Note that the function arguments to
-make_pair are not expressed in terms of call_traits: doing so
-would prevent template argument deduction from functioning.</p>
-
-<h4><a name="ex4"></a>Example 4 (optimising fill):</h4>
-
-<p>The call_traits template will &quot;optimize&quot; the passing
-of a small built-in type as a function parameter, this mainly has
-an effect when the parameter is used within a loop body. In the
-following example (see <a href="algo_opt_examples.cpp">algo_opt_examples.cpp</a>),
-a version of std::fill is optimized in two ways: if the type
-passed is a single byte built-in type then std::memset is used to
-effect the fill, otherwise a conventional C++ implemention is
-used, but with the passed parameter &quot;optimized&quot; using
-call_traits:</p>
-
-<pre>namespace detail{
-
-template &lt;bool opt&gt;
-struct filler
-{
-   template &lt;typename I, typename T&gt;
-   static void do_fill(I first, I last, typename boost::call_traits&lt;T&gt;::param_type val);
-   {
-      while(first != last)
-      {
-         *first = val;
-         ++first;
-      }
-   }
-};
-
-template &lt;&gt;
-struct filler&lt;true&gt;
-{
-   template &lt;typename I, typename T&gt;
-   static void do_fill(I first, I last, T val)
-   {
-      memset(first, val, last-first);
-   }
-};
-
-}
-
-template &lt;class I, class T&gt;
-inline void fill(I first, I last, const T&amp; val)
-{
-   enum{ can_opt = boost::is_pointer&lt;I&gt;::value
-                   &amp;&amp; boost::is_arithmetic&lt;T&gt;::value
-                   &amp;&amp; (sizeof(T) == 1) };
-   typedef detail::filler&lt;can_opt&gt; filler_t;
-   filler_t::template do_fill&lt;I,T&gt;(first, last, val);
-}</pre>
-
-<p>Footnote: the reason that this is &quot;optimal&quot; for
-small built-in types is that with the value passed as &quot;T
-const&quot; instead of &quot;const T&amp;&quot; the compiler is
-able to tell both that the value is constant and that it is free
-of aliases. With this information the compiler is able to cache
-the passed value in a register, unroll the loop, or use
-explicitly parallel instructions: if any of these are supported.
-Exactly how much mileage you will get from this depends upon your
-compiler - we could really use some accurate benchmarking
-software as part of boost for cases like this.</p>
-
-<p>Note that the function arguments to fill are not expressed in
-terms of call_traits: doing so would prevent template argument
-deduction from functioning. Instead fill acts as a &quot;thin
-wrapper&quot; that is there to perform template argument
-deduction, the compiler will optimise away the call to fill all
-together, replacing it with the call to filler&lt;&gt;::do_fill,
-which does use call_traits.</p>
-
-<h3>Rationale</h3>
-
-<p>The following notes are intended to briefly describe the
-rational behind choices made in call_traits.</p>
-
-<p>All user-defined types follow &quot;existing practice&quot;
-and need no comment.</p>
-
-<p>Small built-in types (what the standard calls fundamental
-types [3.9.1]) differ from existing practice only in the <i>param_type</i>
-typedef. In this case passing &quot;T const&quot; is compatible
-with existing practice, but may improve performance in some cases
-(see <a href="#ex4">Example 4</a>), in any case this should never
-be any worse than existing practice.</p>
-
-<p>Pointers follow the same rational as small built-in types.</p>
-
-<p>For reference types the rational follows <a href="#refs">Example
-2</a> - references to references are not allowed, so the
-call_traits members must be defined such that these problems do
-not occur. There is a proposal to modify the language such that
-&quot;a reference to a reference is a reference&quot; (issue #106,
-submitted by Bjarne Stroustrup), call_traits&lt;T&gt;::value_type
-and call_traits&lt;T&gt;::param_type both provide the same effect
-as that proposal, without the need for a language change (in
-other words it's a workaround).</p>
-
-<p>For array types, a function that takes an array as an argument
-will degrade the array type to a pointer type: this means that
-the type of the actual parameter is different from its declared
-type, something that can cause endless problems in template code
-that relies on the declared type of a parameter. For example:</p>
-
-<pre>template &lt;class T&gt;
-struct A
-{
-   void foo(T t);
-};</pre>
-
-<p><font face="Times New Roman">In this case if we instantiate
-A&lt;int[2]&gt; then the declared type of the parameter passed to
-member function foo is int[2], but it's actual type is const int*,
-if we try to use the type T within the function body, then there
-is a strong likelyhood that our code will not compile:</font></p>
-
-<pre>template &lt;class T&gt;
-void A&lt;T&gt;::foo(T t)
-{
-   T dup(t); // doesn't compile for case that T is an array.
-}</pre>
-
-<p>By using call_traits the degradation from array to pointer is
-explicit, and the type of the parameter is the same as it's
-declared type:</p>
-
-<pre>template &lt;class T&gt;
-struct A
-{
-   void foo(typename call_traits&lt;T&gt;::value_type t);
-};
-
-template &lt;class T&gt;
-void A&lt;T&gt;::foo(typename call_traits&lt;T&gt;::value_type t)
-{
-   typename call_traits&lt;T&gt;::value_type dup(t); // OK even if T is an array type.
-}</pre>
-
-<p>For value_type (return by value), again only a pointer may be
-returned, not a copy of the whole array, and again call_traits
-makes the degradation explicit. The value_type member is useful
-whenever an array must be explicitly degraded to a pointer - <a
-href="#ex3">Example 3</a> provides the test case (Footnote: the
-array specialisation for call_traits is the least well understood
-of all the call_traits specialisations, if the given semantics
-cause specific problems for you, or don't solve a particular
-array-related problem, then I would be interested to hear about
-it. Most people though will probably never need to use this
-specialisation).</p>

-
-<p>All of the contents of &lt;boost/compressed_pair.hpp&gt; are
-defined inside namespace boost.</p>
-
-<p>The class compressed pair is very similar to std::pair, but if
-either of the template arguments are empty classes, then the
-&quot;empty member optimisation&quot; is applied to compress the
-size of the pair.</p>
-
-<pre>template &lt;class T1, class T2&gt;
-class compressed_pair
-{
-public:
-	typedef T1                                                 first_type;
-	typedef T2                                                 second_type;
-	typedef typename call_traits&lt;first_type&gt;::param_type       first_param_type;
-	typedef typename call_traits&lt;second_type&gt;::param_type      second_param_type;
-	typedef typename call_traits&lt;first_type&gt;::reference        first_reference;
-	typedef typename call_traits&lt;second_type&gt;::reference       second_reference;
-	typedef typename call_traits&lt;first_type&gt;::const_reference  first_const_reference;
-	typedef typename call_traits&lt;second_type&gt;::const_reference second_const_reference;
-
-	         compressed_pair() : base() {}
-	         compressed_pair(first_param_type x, second_param_type y);
-	explicit compressed_pair(first_param_type x);
-	explicit compressed_pair(second_param_type y);
-
-	compressed_pair&amp; operator=(const compressed_pair&amp;);
-
-	first_reference       first();
-	first_const_reference first() const;
-
-	second_reference       second();
-	second_const_reference second() const;
-
-	void swap(compressed_pair&amp; y);
-};</pre>
-
-<p>The two members of the pair can be accessed using the member
-functions first() and second(). Note that not all member
-functions can be instantiated for all template parameter types.
-In particular compressed_pair can be instantiated for reference
-and array types, however in these cases the range of constructors
-that can be used are limited. If types T1 and T2 are the same
-type, then there is only one version of the single-argument
-constructor, and this constructor initialises both values in the
-pair to the passed value.</p>
-
-<p>Note that compressed_pair can not be instantiated if either of
-the template arguments is a union type, unless there is compiler
-support for boost::is_union, or if boost::is_union is specialised
-for the union type.</p>
-
-<p>Finally, a word of caution for Visual C++ 6 users: if either
-argument is an empty type, then assigning to that member will
-produce memory corruption, unless the empty type has a &quot;do
-nothing&quot; assignment operator defined. This is due to a bug
-in the way VC6 generates implicit assignment operators.</p>

-<p>
-How would you fill up a vector with the numbers zero
-through one hundred using <a
-href="http://www.sgi.com/tech/stl/copy.html"><tt>std::copy()</tt></a>? The
-only iterator operation missing from builtin integer types is an
-<tt>operator*()</tt> that returns the current
-value of the integer.  The counting iterator adaptor adds this crucial piece of
-functionality to whatever type it wraps. One can use the
-counting iterator adaptor not only with integer types, but with any
-type that is <tt>Incrementable</tt> (see type requirements <a href="#requirements">below</a>).  The
-following <b>pseudo-code</b> shows the general idea of how the
-counting iterator is implemented.
-</p>
-
-<pre>
-  // inside a hypothetical counting_iterator class...
-  typedef Incrementable value_type;
-  value_type counting_iterator::operator*() const {
-    return this->base; // no dereference!
-  }
-</pre>
-
-All of the other operators of the counting iterator behave in the same
-fashion as the <tt>Incrementable</tt> base type.

-<h2><a name="counting_iterator_generator">The Counting Iterator Type
-Generator</a></h2>
-
-The class template <tt>counting_iterator_generator&lt;Incrementable&gt;</tt> is a <a href="../../more/generic_programming.html#type_generator">type generator</a> for counting iterators.
-
-<pre>

-{
-public:
-    typedef <a href="./iterator_adaptors.htm#iterator_adaptor">iterator_adaptor</a>&lt;...&gt; type;

-
-<h3>Example</h3>
-
-In this example we use the counting iterator generator to create a
-counting iterator, and count from zero to four.
-
-<pre>
-#include &lt;boost/config.hpp&gt;
-#include &lt;iostream&gt;
-#include &lt;boost/counting_iterator.hpp&gt;
-
-int main(int, char*[])
-{
-  // Example of using counting_iterator_generator
-  std::cout &lt;&lt; "counting from 0 to 4:" &lt;&lt; std::endl;
-  boost::counting_iterator_generator&lt;int&gt;::type first(0), last(4);
-  std::copy(first, last, std::ostream_iterator&lt;int&gt;(std::cout, " "));
-  std::cout &lt;&lt; std::endl;
-
-  // to be continued...

-The output from this part is:

-<h3>Template Parameters</h3>
-
-<Table border>
-<TR>
-<TH>Parameter</TH><TH>Description</TH>
-</TR>
-
-<TR>
-<TD><tt>Incrementable</tt></TD>
-<TD>The type being wrapped by the adaptor.</TD>
-</TR>
-
-</Table>
-
-<h3>Model of</h3>
-
-If the <tt>Incrementable</tt> type has all of the functionality of a
-<a href="http://www.sgi.com/tech/stl/RandomAccessIterator.html">Random
-Access Iterator</a> except the <tt>operator*()</tt>, then the counting
-iterator will be a model of <a
-href="http://www.sgi.com/tech/stl/RandomAccessIterator.html">Random
-Access Iterator</a>. If the <tt>Incrementable</tt> type has less
-functionality, then the counting iterator will have correspondingly
-less functionality.
-
-<h3><a name="requirements">Type Requirements</a></h3>
-
-The <tt>Incrementable</tt> type must be <a
-href="http://www.sgi.com/tech/stl/DefaultConstructible.html">Default
-Constructible</a>, <a href="./CopyConstructible.html">Copy
-Constructible</a>, and <a href="./Assignable.html">Assignable</a>.
-Also, the <tt>Incrementable</tt> type must provide access to an
-associated <tt>difference_type</tt> and <tt>iterator_category</tt>
-through the <a
-href="#counting_iterator_traits"><tt>counting_iterator_traits</tt></a>
-class.
-
-<p>
-Furthermore, if you wish to create a counting iterator that is a <a
-href="http://www.sgi.com/tech/stl/ForwardIterator.html"> Forward
-Iterator</a>, then the following expressions must be valid:
-<pre>
-Incrementable i, j;
-++i         // pre-increment
-i == j      // operator equal
-</pre>
-If you wish to create a counting iterator that is a <a
-href="http://www.sgi.com/tech/stl/BidirectionalIterator.html">
-Bidirectional Iterator</a>, then pre-decrement is also required:
-<pre>
---i
-</pre>
-If you wish to create a counting iterator that is a <a
-href="http://www.sgi.com/tech/stl/RandomAccessIterator.html"> Random
-Access Iterator</a>, then these additional expressions are also required:
-<pre>
-<a href="#counting_iterator_traits">counting_iterator_traits</a>&lt;Incrementable&gt;::difference_type n;
-i += n
-n = i - j
-i < j
-</pre>
-
-
-
-<h3>Members</h3>
-
-The counting iterator type implements the member functions and
-operators required of the <a
-href="http://www.sgi.com/tech/stl/RandomAccessIterator.html">Random
-Access Iterator</a> concept. In addition it has the following
-constructor:
-
-<pre>
-counting_iterator_generator::type(const Incrementable&amp; i)
-</pre>
-
-<p>
-<hr>
-<p>
-
-
-<h2><a name="make_counting_iterator">The Counting Iterator Object Generator</a></h2>
-
-<pre>
-template &lt;class Incrementable&gt;
-typename counting_iterator_generator&lt;Incrementable&gt;::type
-make_counting_iterator(Incrementable base);
-</pre>
-
-An <a href="../../more/generic_programming.html#object_generator">object
-generator</a> function that provides a convenient way to create counting
-iterators.<p>
-
-
-
-<h3>Example</h3>
-
-In this example we count from negative five to positive five, this
-time using the <tt>make_counting_iterator()</tt> function to save some
-typing.
-
-<pre>
-  // continuing from previous example...
-
-  std::cout &lt;&lt; "counting from -5 to 4:" &lt;&lt; std::endl;
-  std::copy(boost::make_counting_iterator(-5),
-	    boost::make_counting_iterator(5),
-	    std::ostream_iterator&lt;int&gt;(std::cout, " "));
-  std::cout &lt;&lt; std::endl;
-
-  // to be continued...
-</pre>
-The output from this part is:
-<pre>
-counting from -5 to 4:
--5 -4 -3 -2 -1 0 1 2 3 4 
-</pre>
-
-In the next example we create an array of numbers, and then create a
-second array of pointers, where each pointer is the address of a
-number in the first array. The counting iterator makes it easy to do
-this since dereferencing a counting iterator that is wrapping an
-iterator over the array of numbers just returns a pointer to the
-current location in the array. We then use the <a
-href="./indirect_iterator.htm">indirect iterator adaptor</a> to print
-out the number in the array by accessing the numbers through the array
-of pointers.
-
-<pre>
-  // continuing from previous example...
-
-  const int N = 7;
-  std::vector&lt;int&gt; numbers;
-  // Fill "numbers" array with [0,N)
-  std::copy(boost::make_counting_iterator(0), boost::make_counting_iterator(N),
-	    std::back_inserter(numbers));
-
-  std::vector&lt;std::vector&lt;int&gt;::iterator&gt; pointers;
-
-  // Use counting iterator to fill in the array of pointers.
-  std::copy(boost::make_counting_iterator(numbers.begin()),
-	    boost::make_counting_iterator(numbers.end()),
-	    std::back_inserter(pointers));
-
-  // Use indirect iterator to print out numbers by accessing
-  // them through the array of pointers.
-  std::cout &lt;&lt; "indirectly printing out the numbers from 0 to " 
-	    &lt;&lt; N &lt;&lt; std::endl;
-  std::copy(boost::make_indirect_iterator(pointers.begin()),
-	    boost::make_indirect_iterator(pointers.end()),
-	    std::ostream_iterator&lt;int&gt;(std::cout, " "));
-  std::cout &lt;&lt; std::endl;
-</pre>
-The output is:
-<pre>
-indirectly printing out the numbers from 0 to 7
-0 1 2 3 4 5 6 
-</pre>

-<h2><a name="counting_iterator_traits">Counting Iterator Traits</a></h2>
-
-The counting iterator adaptor needs to determine the appropriate
-<tt>difference_type</tt> and <tt>iterator_category</tt> to use based on the
-<tt>Incrementable</tt> type supplied by the user.  The
-<tt>counting_iterator_traits</tt> class provides these types.  If the
-<tt>Incrementable</tt> type is an integral type or an iterator, these types
-will be correctly deduced by the <tt>counting_iterator_traits</tt> provided by
-the library. Otherwise, the user must specialize
-<tt>counting_iterator_traits</tt> for her type or add nested typedefs to
-her type to fulfill the needs of
-<a href="http://www.sgi.com/tech/stl/iterator_traits.html">
-<tt>std::iterator_traits</tt></a>.
-
-<p>The following pseudocode describes how the <tt>counting_iterator_traits</tt> are determined:
-
-<pre>
-template &lt;class Incrementable&gt;
-struct counting_iterator_traits
-{
-  if (numeric_limits&lt;Incrementable&gt::is_specialized) {
-    if (!numeric_limits&lt;Incrementable&gt::is_integer)
-       COMPILE_TIME_ERROR;
-
-    if (!numeric_limits&lt;Incrementable&gt::is_bounded
-        &amp;&amp; numeric_limits&lt;Incrementable&gt;::is_signed) {
-        typedef Incrementable difference_type;
-    }
-    else if (numeric_limits&lt;Incrementable&gt::is_integral) {
-        typedef <i>next-larger-signed-type-or-intmax_t</i> difference_type;
-    }
-    typedef std::random_access_iterator_tag iterator_category;   
-  } else {
-    typedef std::iterator_traits&lt;Incrementable&gt;::difference_type difference_type;
-    typedef std::iterator_traits&lt;Incrementable&gt;::iterator_category iterator_category;
-  }
-};
-</pre>
-
-<p>The italicized sections above are implementation details, but it is important
-to know that the <tt>difference_type</tt> for integral types is selected so that
-it can always represent the difference between two values if such a built-in
-integer exists. On platforms with a working <tt>std::numeric_limits</tt>
-implementation, the <tt>difference_type</tt> for any variable-length signed
-integer type <tt>T</tt> is <tt>T</tt> itself.

+[#sec:BOOST_BINARY]
+[section Binary Integer Literals]
+[/===============]
+
+[section Introduction]
+
+The macro `BOOST_BINARY` is used for the representation of binary
+literals. It takes as an argument a binary number arranged as an
+arbitrary amount of 1s and 0s in groupings of length 1 to 8, with
+groups separated by spaces. The macro serves as a replacement for
+[@https://en.cppreference.com/w/cpp/language/integer_literal binary integer literals],
+adopted in C++14.
+
+The type of the literal yielded is determined by the same rules as
+those of [@https://en.cppreference.com/w/cpp/language/integer_literal hex and octal literals].
+By implementation, this macro expands directly to an octal literal during preprocessing, so
+there is no overhead at runtime and the result is usable in any place that an octal literal
+would be.
+
+In order to directly support binary literals with suffixes,
+additional macros of the form `BOOST_BINARY_XXX` are also
+provided, where `XXX` is a standard integer suffix in all capital
+letters.
+
+In addition, LL and ULL suffixes may be used for representing
+`long long` and `unsigned long long` types in compilers which provide
+them as an extension.
+
+The `BOOST_BINARY` family of macros resides in the header
+[@../../../../boost/utility/binary.hpp <boost/utility/binary.hpp>].

+[section Example]
+
+```
+void foo( int );
+
+void foo( unsigned long );
+
+void bar()
+{
+  int value1 = BOOST_BINARY( 100 111000 01 1 110 );
+
+  unsigned long value2 = BOOST_BINARY_UL( 100 001 ); // unsigned long
+
+  long long value3 = BOOST_BINARY_LL( 11 000 ); // long long if supported
+
+  __assert__(    BOOST_BINARY( 10010 )
+          &  BOOST_BINARY( 11000 )
+          == BOOST_BINARY( 10000 )
+        );
+
+  foo( BOOST_BINARY( 1010 ) ); // calls the first foo
+
+  foo( BOOST_BINARY_LU( 1010 ) ); // calls the second foo
+}

+[block'''<?dbhtml stop-chunking?>''']
+
+[section Introduction]
+
+The class templates __base_from_member__ support the base-from-member idiom.
+When developing a class, sometimes a base class needs to be initialized
+with a member of the current class. As a na\u00EFve example:
+
+```
+#include <streambuf>  /* for std::streambuf */
+#include <ostream>    /* for std::ostream */
+
+class fdoutbuf
+  : public __std_streambuf__
+{
+public:
+    explicit fdoutbuf( int fd );
+    //...
+};
+
+class fdostream
+  : public __std_ostream__
+{
+protected:
+    fdoutbuf buf;
+public:
+    explicit fdostream( int fd )
+      : buf( fd ), __std_ostream__( &buf ) {}
+    //...
+};
+```
+
+This is undefined because C++'s initialization order mandates that the base
+class is initialized before the member it uses. [@http://www.moocat.org R.
+Samuel Klatchko] developed a way around this by using the initialization
+order in his favor. Base classes are initialized in order of declaration, so
+moving the desired member to another base class, that is initialized before
+the desired base class, can ensure proper initialization.
+
+A custom base class can be made for this idiom:
+
+    #include <streambuf>  /* for std::streambuf */
+    #include <ostream>    /* for std::ostream */
+
+    class fdoutbuf
+      : public __std_streambuf__
+    {
+    public:
+        explicit fdoutbuf( int fd );
+        //...
+    };
+
+    struct fdostream_pbase
+    {
+        fdoutbuf sbuffer;
+
+        explicit fdostream_pbase( int fd )
+          : sbuffer( fd ) {}
+    };
+
+    class fdostream
+      : private fdostream_pbase
+      , public __std_ostream__
+    {
+        typedef fdostream_pbase  pbase_type;
+        typedef __std_ostream__     base_type;
+
+    public:
+        explicit fdostream( int fd )
+          : pbase_type( fd ), base_type( &sbuffer ) {}
+        //...
+    };
+
+Other projects can use similar custom base classes. The technique is basic
+enough to make a template, with a sample template class in this library.
+The main template parameter is the type of the enclosed member. The
+template class has several (explicit) constructor member templates, which
+implicitly type the constructor arguments and pass them to the member. The
+template class uses implicit copy construction and assignment, cancelling
+them if the enclosed member is non-copyable.
+
+Manually coding a base class may be better if the construction and/or
+copying needs are too complex for the supplied template class, or if the
+compiler is not advanced enough to use it.
+
+Since base classes are unnamed, a class cannot have multiple (direct) base
+classes of the same type. The supplied template class has an extra template
+parameter, an integer, that exists solely to provide type differentiation.
+This parameter has a default value so a single use of a particular member
+type does not need to concern itself with the integer.

+         T8 x8, T9 x9, T10 x10 );
+    #endif
+    };
+
+    template < typename MemberType, int UniqueID >
+    class __base_from_member__<MemberType&, UniqueID>
+    {
+    protected:
+        MemberType& member;
+
+        explicit constexpr __base_from_member__( MemberType& x )
+            noexcept;
+    };
+
+The class template has a first template parameter `MemberType` representing
+the type of the based-member. It has a last template parameter `UniqueID`,
+that is an `int`, to differentiate between multiple base classes that use
+the same based-member type. The last template parameter has a default value
+of zero if it is omitted. The class template has a protected data member
+called `member` that the derived class can use for later base classes or
+itself.
+
+If the appropriate features of C++11 are present, there will be a single
+constructor template. It implements ['perfect forwarding] to the best
+constructor call of `member` if any. The constructor template is marked
+both `constexpr` and `explicit`. The former will be ignored if the
+corresponding inner constructor call of `member` does not have the marker.
+The latter binds the other way; always taking effect, even when the inner
+constructor call does not have the marker. The constructor template
+propagates the `noexcept` status of the inner constructor call. The
+constructor template has a trailing parameter with a default value that
+disables the template when its signature is too close to the signatures of
+the automatically-defined non-template copy- and/or move-constructors of
+__base_from_member__.
+
+On earlier-standard compilers, there is a default constructor and several
+constructor member templates. These constructor templates can take as many
+arguments (currently up to ten) as possible and pass them to a constructor
+of the data member.
+
+A specialization for member references offers a single constructor taking
+a `MemberType&`, which is the only way to initialize a reference.
+
+Since C++ does not allow any way to explicitly state the template parameters
+of a templated constructor, make sure that the arguments are already close
+as possible to the actual type used in the data member's desired constructor.
+Explicit conversions may be necessary.
+
+The `BOOST_BASE_FROM_MEMBER_MAX_ARITY` macro constant specifies the maximum
+argument length for the constructor templates. The constant may be overridden
+if more (or less) argument configurations are needed. The constant may be
+read for code that is expandable like the class template and needs to
+maintain the same maximum size. (Example code would be a class that uses
+this class template as a base class for a member with a flexible set of
+constructors.) This constant is ignored when C++11 features are present.
+

+
+[section Basic Usage]
+
+With the starting example, the `fdoutbuf` sub-object needs to be
+encapsulated in a base class that is inherited before `__std_ostream__`.
+
+```
+#include <boost/utility/base_from_member.hpp>
+
+#include <streambuf>  // for std::streambuf
+#include <ostream>    // for __std_ostream__
+
+class fdoutbuf
+  : public __std_streambuf__
+{
+public:
+    explicit fdoutbuf( int fd );
+    //...
+};
+
+class fdostream
+  : private __boost_base_from_member__<fdoutbuf>
+  , public __std_ostream__
+{
+    // Helper typedef's
+    typedef __boost_base_from_member__<fdoutbuf>  pbase_type;
+    typedef __std_ostream__                        base_type;
+
+public:
+    explicit fdostream( int fd )
+      : pbase_type( fd ), base_type( &member ){}
+    //...
+};
+```
+
+The base-from-member idiom is an implementation detail, so it should not
+be visible to the clients (or any derived classes) of `fdostream`. Due to
+the initialization order, the `fdoutbuf` sub-object will get initialized
+before the `__std_ostream__` sub-object does, making the former sub-object
+safe to use in the latter sub-object's construction. Since the `fdoutbuf`
+sub-object of the final type is the only sub-object with the name `member`
+that name can be used unqualified within the final class.
+
+[endsect]
+
+[section Multiple Sub-Objects]
+
+The base-from-member class templates should commonly involve only one
+base-from-member sub-object, usually for attaching a stream-buffer to an
+I/O stream. The next example demonstrates how to use multiple
+base-from-member sub-objects and the resulting qualification issues.
+
+```
+#include <boost/utility/base_from_member.hpp>
+
+#include <cstddef>  /* for NULL */
+
+struct an_int
+{
+    int  y;
+
+    an_int( float yf );
+};
+
+class switcher
+{
+public:
+    switcher();
+    switcher( double, int * );
+    //...
+};
+
+class flow_regulator
+{
+public:
+    flow_regulator( switcher &, switcher & );
+    //...
+};
+
+template < unsigned Size >
+class fan
+{
+public:
+    explicit fan( switcher );
+    //...
+};
+
+class system
+  : private __boost_base_from_member__<an_int>
+  , private __boost_base_from_member__<switcher>
+  , private __boost_base_from_member__<switcher, 1>
+  , private __boost_base_from_member__<switcher, 2>
+  , protected flow_regulator
+  , public fan<6>
+{
+    // Helper typedef's
+    typedef __boost_base_from_member__<an_int>       pbase0_type;
+    typedef __boost_base_from_member__<switcher>     pbase1_type;
+    typedef __boost_base_from_member__<switcher, 1>  pbase2_type;
+    typedef __boost_base_from_member__<switcher, 2>  pbase3_type;
+
+    typedef flow_regulator  base1_type;
+    typedef fan<6>          base2_type;
+
+public:
+    system( double x );
+    //...
+};
+
+system::system( double x )
+  : pbase0_type( 0.2 )
+  , pbase1_type()
+  , pbase2_type( -16, &this->pbase0_type::member.y )
+  , pbase3_type( x, static_cast<int *>(NULL) )
+  , base1_type( pbase3_type::member, pbase1_type::member )
+  , base2_type( pbase2_type::member )
+{
+    //...
+}
+```
+
+The final class has multiple sub-objects with the name `member`, so any
+use of that name needs qualification by a name of the appropriate base
+type. Using `typedef`s ease mentioning the base types.
+
+However, the fix introduces a new problem when a pointer is needed. Using the
+address operator with a sub-object qualified with its class's name results in a
+pointer-to-member (here, having a type of `an_int __boost_base_from_member__<an_int, 0>::*`)
+instead of a pointer to the member (having a type of `an_int*`).
+The new problem is fixed by qualifying the sub-object with `this->` and is needed
+just for pointers, and not for references or values.
+
+There are some argument conversions in the initialization. The constructor
+argument for `pbase0_type` is converted from `double` to `float`. The first
+constructor argument for `pbase2_type` is converted from `int` to `double`.
+
+The second constructor argument for `pbase3_type` is a special case of
+necessary conversion; all forms of the null-pointer literal in C++ (except
+`nullptr` from C++11) also look like compile-time integral expressions, so
+C++ always interprets such code as an integer when it has overloads that can
+take either an integer or a pointer.
+
+The last conversion is necessary for the compiler to call a constructor form
+with the exact pointer type used in `switcher`'s constructor. (If C++11's
+__nullptr__ is used, it still needs a conversion if multiple pointer types can
+be accepted in a constructor call but `__std_nullptr_t__` cannot.)

+[section Call Traits]
+[/===============]
+
+[section Introduction]
+
+All of the contents of [@../../../../boost/call_traits.hpp `<boost/call_traits.hpp>`] are
+defined inside `namespace boost`.
+
+The template class __call_traits_T__ encapsulates the
+"best" method to pass a parameter of some type `T` to or
+from a function, and consists of a collection of `typedef`s defined
+as in the table below. The purpose of __call_traits__ is to ensure
+that problems like [link sec:refs "references to references"]
+never occur, and that parameters are passed in the most efficient
+manner possible, as in the [link sec:examples examples]. In each
+case, if your existing practice is to use the type defined on the
+left, then replace it with the __call_traits__ defined type on the
+right.
+
+Note that for compilers that do not support either partial
+specialization or member templates, no benefit will occur from
+using __call_traits__: the __call_traits__ defined types will always be
+the same as the existing practice in this case. In addition if
+only member templates and not partial template specialisation is
+support by the compiler (for example Visual C++ 6) then
+__call_traits__ cannot be used with array types, although it can still be
+used to solve the reference to reference problem.

+
+Notes:
+
+# If `T` is already reference type, then __call_traits__ is
+        defined such that [link sec:refs "references to references"]
+        do not occur (requires partial specialization).
+# If `T` is an array type, then __call_traits__ defines `value_type`
+        as a "constant pointer to type" rather than an
+        "array of type" (requires partial specialization).
+        Note that if you are using `value_type` as a stored value
+        then this will result in storing a "constant pointer to
+        an array" rather than the array itself. This may or may
+        not be a good thing depending upon what you actually
+        need (in other words take care!).
+# If `T` is a small built in type or a pointer, then `param_type`
+        is defined as `T const`, instead of `T const&`. This can
+        improve the ability of the compiler to optimize loops in
+        the body of the function if they depend upon the passed
+        parameter, the semantics of the passed parameter is
+        otherwise unchanged (requires partial specialization).

+
+The table assumes the compiler supports partial
+specialization: if it does not then all types behave in
+the same way as the entry for "`my_class`", and
+__call_traits__ can not be used with reference or array types.
+
+[section Example 1:]
+
+The following class is a trivial class that stores some type `T`
+by value (see the [@../../../test/call_traits_test.cpp `call_traits_test.cpp`]
+file). The aim is to illustrate how each of the available
+__call_traits__ `typedef`s may be used:
+
+```
+template <class T>
+struct contained
+{
+   // define our typedefs first, arrays are stored by value
+   // so value_type is not the same as result_type:
+   typedef typename __boost_call_traits__<T>::param_type       param_type;
+   typedef typename __boost_call_traits__<T>::reference        reference;
+   typedef typename __boost_call_traits__<T>::const_reference  const_reference;
+   typedef T                                                value_type;
+   typedef typename __boost_call_traits__<T>::value_type       result_type;
+
+   // stored value:
+   value_type v_;
+
+   // constructors:
+   contained() {}
+   contained(param_type p) : v_(p){}
+   // return byval:
+   result_type value() { return v_; }
+   // return by_ref:
+   reference get() { return v_; }
+   const_reference const_get()const { return v_; }
+   // pass value:
+   void call(param_type p){}
+
+};
+```
+[endsect]
+
+[#sec:refs]
+[section Example 2 (the reference to reference problem):]
+
+Consider the definition of __std_binder1st__:
+
+```
+template <class Operation>
+class binder1st :
+   public __std_unary_function__<typename Operation::second_argument_type, typename Operation::result_type>
+{
+protected:
+   Operation op;
+   typename Operation::first_argument_type value;
+public:
+   binder1st(const Operation& x, const typename Operation::first_argument_type& y);
+   typename Operation::result_type operator()(const typename Operation::second_argument_type& x) const;
+};
+```
+
+Now consider what happens in the relatively common case that
+the functor takes its second argument as a reference, that
+implies that `Operation::second_argument_type` is a
+reference type, `operator()` will now end up taking a
+reference to a reference as an argument, and that is not
+currently legal. The solution here is to modify `operator()`
+to use __call_traits__:
+
+```
+typename Operation::result_type operator()(typename __call_traits__<typename Operation::second_argument_type>::param_type x) const;
+```
+
+Now in the case that `Operation::second_argument_type`
+is a reference type, the argument is passed as a reference, and
+the no "reference to reference" occurs.
+
+[endsect]
+
+[#sec:example3]
+[section Example 3 (the `make_pair` problem):]
+
+If we pass the name of an array as one (or both) arguments to `__std_make_pair__`,
+then template argument deduction deduces the passed parameter as
+"const reference to array of `T`", this also applies to
+string literals (which are really array literals). Consequently
+instead of returning a pair of pointers, it tries to return a
+pair of arrays, and since an array type is not copy-constructible
+the code fails to compile. One solution is to explicitly cast the
+arguments to __std_make_pair__ to pointers, but __call_traits__ provides a
+better automatic solution that works safely even in generic code where the
+cast might do the wrong thing:
+
+```
+template <class T1, class T2>
+__std_pair__<
+   typename __boost_call_traits__<T1>::value_type,
+   typename __boost_call_traits__<T2>::value_type>
+      make_pair(const T1& t1, const T2& t2)
+{
+   return __std_pair__<
+      typename __boost_call_traits__<T1>::value_type,
+      typename __boost_call_traits__<T2>::value_type>(t1, t2);
+}
+```
+
+Here, the deduced argument types will be automatically
+degraded to pointers if the deduced types are arrays, similar
+situations occur in the standard binders and adapters: in
+principle in any function that "wraps" a temporary
+whose type is deduced. Note that the function arguments to
+__std_make_pair__ are not expressed in terms of __call_traits__: doing so
+would prevent template argument deduction from functioning.
+[endsect]
+
+[#sec:example4]
+[section Example 4 (optimising fill):]
+
+The __call_traits__ template will "optimize" the passing
+of a small built-in type as a function parameter. This mainly has
+an effect when the parameter is used within a loop body.
+
+In the following example (see [@boost:/libs/type_traits/examples/fill_example.cpp `fill_example.cpp`]),
+a version of __std_fill__ is optimized in two ways: if the type
+passed is a single byte built-in type then __std_memset__ is used to
+effect the fill, otherwise a conventional C++ implementation is
+used, but with the passed parameter "optimized" using
+__call_traits__:
+
+```
+template <bool opt>
+struct filler
+{
+   template <typename I, typename T>
+   static void do_fill(I first, I last, typename __boost_call_traits__<T>::param_type val)
+   {
+      while(first != last)
+      {
+         *first = val;
+         ++first;
+      }
+   }
+};
+
+template <>
+struct filler<true>
+{
+   template <typename I, typename T>
+   static void do_fill(I first, I last, T val)
+   {
+      __std_memset__(first, val, last-first);
+   }
+};
+
+template <class I, class T>
+inline void fill(I first, I last, const T& val)
+{
+   enum { can_opt = boost::is_pointer<I>::value
+                   && boost::is_arithmetic<T>::value
+                   && (sizeof(T) == 1) };
+   typedef filler<can_opt> filler_t;
+   filler_t::template do_fill<I,T>(first, last, val);
+}
+```
+
+The reason that this is "optimal" for small built-in types is that
+with the value passed as `T const` instead of `const T&` the compiler is
+able to tell both that the value is constant and that it is free
+of aliases. With this information the compiler is able to cache
+the passed value in a register, unroll the loop, or use
+explicitly parallel instructions: if any of these are supported.
+Exactly how much mileage you will get from this depends upon your
+compiler - we could really use some accurate benchmarking
+software as part of boost for cases like this.
+
+Note that the function arguments to fill are not expressed in
+terms of __call_traits__: doing so would prevent template argument
+deduction from functioning. Instead fill acts as a "thin
+wrapper" that is there to perform template argument
+deduction, the compiler will optimise away the call to fill all
+together, replacing it with the call to `filler<>::do_fill`,
+which does use __call_traits__.
+
+[endsect]
+[endsect]
+
+[section Rationale]
+
+The following notes are intended to briefly describe the
+rationale behind choices made in __call_traits__.
+
+All user-defined types follow "existing practice" and need no comment.
+
+Small built-in types, what the standard calls [@https://en.cppreference.com/w/cpp/language/types fundamental
+types], differ from existing practice only in the `param_type`
+`typedef`. In this case passing `T const` is compatible
+with existing practice, but may improve performance in some cases
+(see [link sec:example4 Example 4]). In any case this should never
+be any worse than existing practice.
+
+Pointers follow the same rationale as small built-in types.
+
+For reference types the rationale follows [link sec:refs Example 2]
+- references to references are not allowed, so the __call_traits__
+members must be defined such that these problems do
+not occur. There is a proposal to modify the language such that
+"a reference to a reference is a reference" (issue #106,
+submitted by Bjarne Stroustrup). __call_traits_T__`::value_type`
+and __call_traits_T__`::param_type` both provide the same effect
+as that proposal, without the need for a language change. In
+other words, it's a workaround.
+
+For array types, a function that takes an array as an argument
+will degrade the array type to a pointer type: this means that
+the type of the actual parameter is different from its declared
+type, something that can cause endless problems in template code
+that relies on the declared type of a parameter.
+
+For example:
+
+```
+template <class T>
+struct A
+{
+   void foo(T t);
+};
+```
+
+In this case if we instantiate `A<int[2]>` then the declared type of
+the parameter passed to member function `foo` is `int[2]`, but its
+actual type is `const int*`. If we try to use the type `T` within the
+function body, then there is a strong likelihood that our code will not compile:
+
+```
+template <class T>
+void A<T>::foo(T t)
+{
+   T dup(t); // doesn't compile for case that T is an array.
+}
+```
+
+By using __call_traits__ the degradation from array to pointer is
+explicit, and the type of the parameter is the same as it's
+declared type:
+
+```
+template <class T>
+struct A
+{
+   void foo(typename __call_traits__<T>::value_type t);
+};
+
+template <class T>
+void A<T>::foo(typename __call_traits__<T>::value_type t)
+{
+   typename __call_traits__<T>::value_type dup(t); // OK even if T is an array type.
+}
+```
+
+For `value_type` (return by value), again only a pointer may be
+returned, not a copy of the whole array, and again __call_traits__
+makes the degradation explicit. The `value_type` member is useful
+whenever an array must be explicitly degraded to a pointer -
+[link sec:example3 Example 3] provides the test case.
+
+Footnote: the array specialisation for __call_traits__ is the least
+well understood of all the __call_traits__ specialisations. If the given
+semantics cause specific problems for you, or does not solve a particular
+array-related problem, then I would be interested to hear about
+it. Most people though will probably never need to use this
+specialisation.

+[section Compressed Pair]
+
+[section Introduction]
+
+All of the contents of [@../../../../boost/compressed_pair.hpp `<boost/compressed_pair.hpp>`] are defined inside
+`namespace boost`.
+
+The class __compressed_pair__ is very similar to __std_pair__. However, if either of
+the template arguments are empty classes, then the
+[@https://en.cppreference.com/w/cpp/language/ebo ['empty base-class optimisation]]
+is applied to compress the size of the pair.
+
+[endsect]
+
+[section Synopsis]
+
+```cpp
+template <class T1, class T2>
+class __compressed_pair__
+{
+public:
+    typedef T1                                                 first_type;
+    typedef T2                                                 second_type;
+    typedef typename __call_traits__<first_type>::param_type       first_param_type;
+    typedef typename __call_traits__<second_type>::param_type      second_param_type;
+    typedef typename __call_traits__<first_type>::reference        first_reference;
+    typedef typename __call_traits__<second_type>::reference       second_reference;
+    typedef typename __call_traits__<first_type>::const_reference  first_const_reference;
+    typedef typename __call_traits__<second_type>::const_reference second_const_reference;
+
+             compressed_pair() : base() {}
+             compressed_pair(first_param_type x, second_param_type y);
+    explicit compressed_pair(first_param_type x);
+    explicit compressed_pair(second_param_type y);
+
+    compressed_pair& operator=(const compressed_pair&);
+
+    first_reference       first();
+    first_const_reference first() const;
+
+    second_reference       second();
+    second_const_reference second() const;
+
+    void swap(compressed_pair& y);
+};
+```
+
+The two members of the pair can be accessed using the member functions
+`first()` and `second()`. Note that not all member functions can be
+instantiated for all template parameter types. In particular
+__compressed_pair__ can be instantiated for reference and array types,
+however in these cases the range of constructors that can be used is
+limited. If types `T1` and `T2` are the same type, then there is only
+one version of the single-argument constructor, and this constructor
+initialises both values in the pair to the passed value.
+
+Note that if either member is a [@https://en.cppreference.com/w/cpp/named_req/PODType POD]
+type, then that member is not zero-initialized by the __compressed_pair__ default constructor:
+it is up to you to supply an initial value for these types if you want them to have
+a default value.
+
+Note that __compressed_pair__ can not be instantiated if either of the
+template arguments is a union type, unless there is compiler support for
+[@boost:/libs/type_traits/index.html `boost::is_union`], or
+if [@boost:/libs/type_traits/index.html `boost::is_union`] is
+specialised for the union type.
+
+Finally, a word of caution for Visual C++ 6 users: if either argument is an
+empty type, then assigning to that member will produce memory corruption,
+unless the empty type has a "do nothing" assignment operator defined. This
+is due to a bug in the way VC6 generates implicit assignment operators.

+[section In-place Factory]
+[/===============]
+
+[section Introduction]
+
+Suppose we have a class
+
+```
+struct X
+{
+  X ( int, __std_string__ ) ;
+};
+```
+
+And a container for it which supports an empty state. That is, a container which can contain zero objects:
+
+```
+struct C
+{
+   C() : contained_(0) {}
+  ~C() { delete contained_ ; }
+  X* contained_ ;
+};
+```
+
+A container designed to support an empty state typically does not require the contained type to be
+__DefaultConstructible__, but it typically requires it to be __CopyConstructible__ as a mechanism to
+initialize the object to store:
+
+```
+struct C
+{
+   C() : contained_(0) {}
+   C ( X const& v ) : contained_ ( new X(v) ) {}
+  ~C() { delete contained_ ; }
+  X* contained_ ;
+};
+```
+
+There is a subtle problem with this: since the mechanism used to initialize the stored object is copy construction,
+there must exist a previously constructed source object to copy from. This object is likely to be temporary and serve
+no purpose besides being the source:
+
+```
+void foo()
+{
+  // Temporary object created.
+  C c( X(123,"hello") ) ;
+}
+```
+
+A solution to this problem is to support direct construction of the contained
+object right in the container's storage.
+
+In this scheme, the user supplies the arguments for the `X` constructor
+directly to the container:
+
+```
+struct C
+{
+   C() : contained_(0) {}
+   C ( X const& v ) : contained_ ( new X(v) ) {}
+   C ( int a0, __std_string__ a1 ) : contained_ ( new X(a0,a1) ) {}
+  ~C() { delete contained_ ; }
+  X* contained_ ;
+};
+```
+
+```
+void foo()
+{
+  // Wrapped object constructed in-place
+  // No temporary created.
+  C c(123,"hello");
+}
+```
+
+Clearly, this solution does not scale well since the container must duplicate all the constructor overloads
+from the contained type, or at least all those which are to be supported directly in the container.
+
+[endsect]
+[section Framework]
+
+This library proposes a framework to allow some containers to directly construct contained objects in-place without requiring
+the entire set of constructor overloads from the contained type. It also allows the container to remove the __CopyConstructible__
+requirement from the contained type since objects can be directly constructed in-place without need of a copy.
+
+The only requirement on the container is that it must provide proper storage. That is, the container should be
+correctly aligned and sized. Naturally, the container will typically support uninitialized storage to avoid the
+in-place construction to override a fully-constructed object, as this would defeat the purpose of in-place construction.
+
+For this purpose, the framework provides two concepts called: InPlaceFactories and TypedInPlaceFactories.
+Helpers to declare these classes are declared in [@../../../../boost/utility/in_place_factory.hpp `<boost/utility/in_place_factory.hpp>`]
+and [@../../../../boost/utility/typed_in_place_factory.hpp `<boost/utility/typed_in_place_factory.hpp>`].
+
+Essentially, these classes hold a sequence of actual parameters and a method to construct an object in place using these parameters.
+Each member of the family differs only in the number and type of the parameter list. The first family
+takes the type of the object to construct directly in method provided for that
+purpose, whereas the second family incorporates that type in the factory class
+itself. From the container point of view, using the framework amounts to calling the
+factory's method to contruct the object in place. From the user point of view, it amounts to creating
+the right factory object to hold the parameters and pass it to the container.
+
+The following simplified example shows the basic idea. A complete example follows the formal specification of the framework:
+
+```
+struct C
+{
+   template <class InPlaceFactory>
+   C ( InPlaceFactory const& aFactory )
+    :
+    contained_ ( uninitialized_storage() )
+   {
+     aFactory.template apply<X>(contained_);
+   }
+
+  ~C()
+  {
+    contained_ -> X::~X();
+    delete[] contained_ ;
+  }
+
+  char* uninitialized_storage() { return new char[sizeof(X)] ; }
+
+  char* contained_ ;
+};
+
+void foo()
+{
+  C c( in_place(123,"hello") ) ;
+}
+
+```
+
+[endsect]
+[section Specification]
+
+The following is the first member of the family of `InPlaceFactory` classes, along with its corresponding helper template function.
+The rest of the family varies only in the number and type of template and constructor parameters.
+
+
+```
+namespace boost {
+
+struct __in_place_factory_base__ {};
+
+template<class A0>
+class in_place_factory : public __in_place_factory_base__
+{
+  public:
+    in_place_factory ( A0 const& a0 ) : m_a0(a0) {}
+
+    template< class T >
+    void apply ( void* address ) const
+    {
+      new (address) T(m_a0);
+    }
+
+  private:
+      A0 const& m_a0 ;
+};
+
+template<class A0>
+in_place_factory<A0> in_place ( A0 const& a0 )
+{
+  return in_place_factory<A0>(a0);
+}
+
+}
+```
+
+Similarly, the following is the first member of the family of `typed_in_place_factory` classes, along with its corresponding
+helper template function. The rest of the family varies only in the number and type of template and constructor parameters.
+
+```
+namespace boost {
+
+struct __typed_in_place_factory_base__ {};
+
+template<class T, class A0>
+class typed_in_place_factory : public __typed_in_place_factory_base__
+{
+  public:
+    typed_in_place_factory ( A0 const& a0 ) : m_a0(a0) {}
+
+    void apply ( void* address ) const
+    {
+      new (address) T(m_a0);
+    }
+
+  private:
+    A0 const& m_a0 ;
+};
+
+template<class T, class A0>
+typed_in_place_factory<A0> in_place ( A0 const& a0 )
+{
+  return typed_in_place_factory<T,A0>(a0);
+}
+}
+```
+
+As you can see, the `in_place_factory` and `typed_in_place_factory` template classes vary only in the way they specify
+the target type: in the first family, the type is given as a template argument to the apply member function while in the
+second it is given directly as part of the factory class.
+
+When the container holds a unique non-polymorphic type, such as the case of [@boost:/libs/optional/index.html Boost.Optional],
+it knows the exact dynamic-type of the contained object and can pass it to the `apply()` method of a non-typed factory.
+In this case, end users can use an `in_place_factory` instance which can be constructed without the type of the object to construct.
+
+However, if the container holds heterogeneous or polymorphic objects, such as the case of [@boost:/libs/variant/index.html Boost.Variant],
+the dynamic-type of the object to be constructed must be known by the factory. In this case, end users must use a `typed_in_place_factory`
+instead.
+
+[endsect]
+[section Container-side Usage]
+
+As shown in the introductory simplified example, the container class must contain methods that accept an instance of
+these factories and pass the object's storage to the factory's apply method.
+
+However, the type of the factory class cannot be completely specified in the container class because that would
+defeat the whole purpose of the factories which is to allow the container to accept a variadic argument list
+for the constructor of its contained object.
+
+The correct function overload must be based on the only distinctive and common
+characteristic of all the classes in each family: the base class.
+
+Depending on the container class, you can use `enable_if` to generate the right overload, or use the following
+dispatch technique, which is used in the [@boost:/libs/optional/index.html Boost.Optional] class:
+
+
+```
+struct C
+{
+   C() : contained_(0) {}
+   C ( X const& v ) : contained_ ( new X(v) ) {}
+
+   template <class Expr>
+   C ( Expr const& expr )
+    :
+    contained_ ( uninitialized_storage() )
+   {
+    construct(expr,&expr);
+   }
+
+  ~C() { delete contained_ ; }
+
+  template<class InPlaceFactory>
+  void construct ( InPlaceFactory const& aFactory, boost::__in_place_factory_base__* )
+  {
+    aFactory.template apply<X>(contained_);
+  }
+
+  template<class TypedInPlaceFactory>
+  void construct ( TypedInPlaceFactory const& aFactory, boost::__typed_in_place_factory_base__* )
+  {
+    aFactory.apply(contained_);
+  }
+
+  X* uninitialized_storage() { return static_cast<X*>(new char[sizeof(X)]) ; }
+
+  X* contained_ ;
+};
+```
+
+[endsect]
+[section User-side Usage]
+
+End users pass to the container an instance of a factory object holding the actual parameters needed to construct the
+contained object directly within the container. For this, the helper template function `in_place` is used.
+
+The call `in_place(a0,a1,a2,...,an)` constructs a (non-typed) `in_place_factory` instance with the given argument list.
+
+The call `in_place<T>(a0,a1,a2,...,an)` constructs a `typed_in_place_factory` instance with the given argument list for the
+type `T`.
+
+```
+void foo()
+{
+  C a( in_place(123, "hello") ) ;    // in_place_factory passed
+  C b( in_place<X>(456, "world") ) ; // typed_in_place_factory passed
+}
+
+```

+[section Overview]
+[block'''<?dbhtml stop-chunking?>''']
+
+Boost.Utility is a collection of small, useful, and general-purpose components for language support.
+
+Over time,
+
+* several components have been moved to more appropriate Boost libraries and
+* many of these components had variants accepted into the C++ standard
+
+When the component has moved to another Boost library, Boost.Utility headers still lead to the appropriate headers
+in other libraries.

+[section Result of]
+[/===============]
+
+[section Introduction]
+
+The class template __result_of__ helps determine the type of a
+call expression. For example, given an lvalue `f` of type `F`
+and lvalues `t1`,`t2`, ..., `tN` of types `T1`, `T2`, ..., `TN`,
+respectively, the type __result_of__`<F(T1, T2, ..., TN)>::type` defines
+the result type of the expression `f(t1, t2, ...,tN)`.
+
+This implementation permits the type `F` to be a function pointer,
+function reference, member function pointer, or class type. By default,
+N may be any value between 0 and 16. To change the upper limit, define
+the macro `BOOST_RESULT_OF_NUM_ARGS` to the maximum value for N. Class
+template __result_of__ resides in the header
+[@../../../../boost/utility/result_of.hpp `<boost/utility/result_of.hpp>`].
+
+If your compiler's support for __decltype__ is adequate, __result_of__
+automatically uses it to deduce the type of the call expression, in
+which case __result_of__`<F(T1, T2, ..., TN)>::type` names the type
+__decltype__`(boost::declval<F>()(boost::declval<T1>(),
+boost::declval<T2>(), ..., boost::declval<TN>()))`, as in the
+following example.
+
+```
+struct functor {
+    template<class T>
+    T operator()(T x)
+    {
+        return x;
+    }
+};
+
+typedef __boost_result_of__<functor(int)>::type type; // type is int
+```
+
+You can test whether __result_of__ is using __decltype__ by checking if
+the macro `BOOST_RESULT_OF_USE_DECLTYPE` is defined after
+including `result_of.hpp`. You can also force __result_of__ to use
+__decltype__ by defining `BOOST_RESULT_OF_USE_DECLTYPE` prior
+to including `result_of.hpp`.
+
+If __decltype__ is not used, then automatic result type deduction of function
+objects is not possible. Instead, __result_of__ uses the following protocol
+to allow the programmer to specify a type. When `F` is a class type with a
+member type `result_type`, `result_of<F(T1, T2, ..., TN)>::type` is
+`F::result_type`. When `F` does not contain `result_type`,
+`result_of<F(T1, T2, ..., TN)>::type` is
+`F::result<F(T1, T2, ..., TN)>::type` when
+`N > 0` or `void` when `N = 0`.
+
+Note that it is the responsibility of the programmer to ensure that
+function objects accurately advertise their result
+type via this protocol, as in the following example.
+
+```
+struct functor {
+    template <class> struct result;
+
+    template<class F, class T>
+    struct result<F(T)> {
+        typedef T type;
+    };
+
+    template<class T>
+    T operator()(T x)
+    {
+        return x;
+    }
+};
+
+typedef __boost_result_of__<functor(int)>::type type; // type is int
+```
+
+Since __decltype__ is a language feature standardized in C++11, if you are
+writing a function object to be used with __result_of__, for maximum
+portability, you might consider following the above protocol
+even if your compiler has proper __decltype__ support.
+
+If you wish to continue to use the protocol on compilers that
+support __decltype__, there are two options:
+
+* You can use __boost_tr1_result_of__, which is also defined in
+[@../../../boost/utility/result_of.hpp `<boost/utility/result_of.hpp>`].
+
+* Alternatively, you can define the macro `BOOST_RESULT_OF_USE_TR1`,
+which causes __result_of__ to use the protocol described above instead
+of __decltype__. If you choose to follow the protocol, take care to
+ensure that the `result_type` and `result<>` members accurately
+represent the return type of `operator()` given a call expression.
+
+Additionally, __boost_result_of__ provides a third mode of operation,
+which some users may find convenient. When
+`BOOST_RESULT_OF_USE_TR1_WITH_DECLTYPE_FALLBACK` is defined,
+__boost_result_of__ behaves as follows. If the function object has a member
+type `result_type` or member template `result<>`, then __boost_result_of__
+will use the TR1 protocol.
+
+Otherwise, __boost_result_of__ will use __decltype__. Using TR1 with
+a __decltype__ fallback may workaround certain problems at the cost of portability.
+For example:
+
+* Deficient compiler: If your code requires __boost_result_of__ to work
+with incomplete return types but your compiler's __decltype__ implementation
+does not support incomplete return types, then you can use the TR1 protocol
+as a workaround. Support for incomplete return types was added late in the
+C++11 standardization process
+(see [@http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2011/n3276.pdf N3276])
+and is not implemented by some compilers.
+
+* Deficient legacy code: If your existing TR1 function object advertises a different type than
+the actual result type deduced by __decltype__, then using TR1 with a __decltype__ fallback
+will allow you to work with both your existing TR1 function objects and new C++11
+function object. This situation could occur if your legacy function objects
+misused the TR1 protocol. See the documentation on known [link sec:result_of_tr1_diff differences]
+between __boost_result_of__ and TR1.
+
+* [#BOOST_NO_RESULT_OF] This implementation of __result_of__ requires class template
+partial specialization, the ability to parse function types properly, and support
+for SFINAE. If __result_of__ is not supported by your compiler, including the header
+[@../../../boost/utility/result_of.hpp `<boost/utility/result_of.hpp>`] will define
+the macro `BOOST_NO_RESULT_OF`.
+
+For additional information about __result_of__, see the C++ Library
+Technical Report, [@http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2005/n1836.pdf N1836],
+or, for motivation and design rationale, the __result_of__

+[#sec:result_of_guidelines]
+[section Usage guidelines for __boost_result_of__]
+
+The following are general suggestions about when and how to use __boost_result_of__.
+
+# If you are targeting C++11 and are not concerned about portability to
+non-compliant compilers or previous versions of the standard, then use
+`__std_result_of__`. If `__std_result_of__` meets your needs, then
+there's no reason to stop using it.
+
+# If you are targeting C++11 but may port your code to legacy compilers
+at some time in the future, then use __boost_result_of__ with __decltype__.
+When __decltype__ is used __boost_result_of__ and `__std_result_of__` are usually
+interchangeable. See the documentation on known [link sec:result_of_cxx11_diff differences]
+between __boost_result_of__ and C++11 __std_result_of__.
+
+# If compiler portability is required, use __boost_result_of__ with the TR1 protocol
+
+Regardless of how you configure __boost_result_of__, it is
+important to bear in mind that the return type of a
+function may change depending on its arguments, and
+additionally, the return type of a member function may
+change depending on the cv-qualification of the
+object. __boost_result_of__ must be passed
+the appropriately cv-qualified types in order to
+deduce the corresponding return type.
+
+For example:
+
+```
+struct functor {
+    int& operator()(int);
+    int const& operator()(int) const;
+
+    float& operator()(float&);
+    float const& operator()(float const&);
+};
+
+typedef __boost_result_of__<
+    functor(int)
+>::type type1; // type1 is int &
+
+typedef __boost_result_of__<
+    const functor(int)
+>::type type2; // type2 is int const &
+
+typedef __boost_result_of__<
+    functor(float&)
+>::type type3; // type3 is float &
+
+typedef __boost_result_of__<
+    functor(float const&)
+>::type type4; // type4 is float const &
+```
+
+[endsect]
+
+[#sec:result_of_tr1_protocol_guidelines]
+[section Usage guidelines for the TR1 result_of protocol]
+
+On compliant C++11 compilers, __boost_result_of__ can
+use __decltype__ to deduce the type of any
+call expression, including calls to function
+objects. However, on pre-C++11 compilers or on
+compilers without adequate decltype support,
+additional scaffolding is needed from function
+objects as described above. The following are
+suggestions about how to use the TR1 protocol.
+
+* When the return type does not depend on the
+argument types or the cv-qualification of the
+function object, simply
+define `result_type`. There is no need
+to use the `result` template unless the
+return type varies.</li>
+
+* Use the protocol specified type when defining
+function prototypes. This can help ensure the
+actual return type does not get out of sync with
+the protocol specification. For example:
+
+```
+struct functor {
+    typedef int result_type;
+    result_type operator()(int);
+};
+```
+
+* Always specify the `result` specialization near the corresponding
+`operator()` overload. This can make it easier to keep the specializations
+in sync with the overloads. For example:
+
+```
+struct functor {
+    template<class> struct result;
+
+    template<class F>
+    struct result<F(int)> {
+        typedef int& type;
+    };
+    result<functor(int)>::type operator()(int);
+
+    template<class F>
+    struct result<const F(int)> {
+        typedef int const& type;
+    };
+    result<const functor(int)>::type operator()(int) const;
+};
+```
+
+* Use type transformations to simplify
+the `result` template specialization. For
+example, the following uses [@../type_traits/doc/html/index.html Boost.TypeTraits]
+to specialize the `result` template for
+a single `operator()` that can be called on
+both a const and non-const function object with
+either an lvalue or rvalue argument.
+
+```
+struct functor {
+    template<class> struct result;
+
+    template<class F, class T>
+    struct result<F(T)>
+        : boost::remove_cv<
+              typename boost::remove_reference<T>::type
+          >
+    {};
+
+    template<class T>
+    T operator()(T const&amp; x) const;
+};
+```

+
+[#sec:result_of_tr1_diff]
+[section Known differences between __boost_result_of__ and __boost_tr1_result_of__]
+
+When using __decltype__, __boost_result_of__ ignores the TR1 protocol and instead deduces the
+return type of function objects directly via __decltype__. In most situations, users
+will not notice a difference, so long as they use the protocol correctly. The following are situations in
+which the type deduced by __boost_result_of__ is known to differ depending on whether
+__decltype__ or the TR1 protocol is used.
+
+TR1 protocol misusage: When using the TR1 protocol, __boost_result_of__ cannot
+detect whether the actual type of a call to a function object is the same as the
+type specified by the protocol, which allows for the possibility of inadvertent
+mismatches between the specified type and the actual type. When using __decltype__,
+these subtle bugs may result in compilation errors. For example:
+
+```
+struct functor {
+   typedef short result_type;
+   int operator()(short);
+};
+
+#ifdef BOOST_RESULT_OF_USE_DECLTYPE
+
+BOOST_STATIC_ASSERT((
+   boost::is_same<__boost_result_of__<functor(short)>::type, int>::value
+));
+
+#else
+
+BOOST_STATIC_ASSERT((
+   boost::is_same<__boost_result_of__<functor(short)>::type, short>::value
+));
+
+#endif
+```
+
+Note that the user can force __boost_result_of__ to use the TR1
+protocol even on platforms that support __decltype__ by
+defining `BOOST_RESULT_OF_USE_TR1`.
+
+Nullary function objects: When using the TR1 protocol, __boost_result_of__
+cannot always deduce the type of calls to nullary function objects, in which case the
+type defaults to void. When using __decltype__, __boost_result_of__ always gives the
+actual type of the call expression. For example:
+
+```
+struct functor {
+   template<class> struct result {
+       typedef int type;
+   };
+   int operator()();
+};
+
+#ifdef BOOST_RESULT_OF_USE_DECLTYPE
+
+BOOST_STATIC_ASSERT((
+   boost::is_same<__boost_result_of__<functor()>::type, int>::value
+));
+
+#else
+
+BOOST_STATIC_ASSERT((
+   boost::is_same<__boost_result_of__<functor()>::type, void>::value
+));
+
+#endif
+```
+
+Note that there are some workarounds for the nullary function problem.
+So long as the return type does not vary, `result_type` can always be used to
+specify the return type regardless of arity. If the return type does vary,
+then the user can specialize __boost_result_of__ itself for nullary calls.
+
+Non-class prvalues and cv-qualification: When using the TR1 protocol, __boost_result_of__ will
+report the cv-qualified type specified by `result_type` or the `result` template regardless of
+the actual cv-qualification of the call expression. When using __decltype__, __boost_result_of__
+will report the actual type of the call expression, which is not cv-qualified when the expression
+is a non-class prvalue. For example:
+
+```
+struct functor {
+   template<class> struct result;
+   template<class F, class T> struct result<F(const T)> {
+       typedef const T type;
+   };
+
+   const short operator()(const short);
+   int const & operator()(int const &);
+};
+
+// Non-prvalue call expressions work the same with or without decltype.
+
+BOOST_STATIC_ASSERT((
+   boost::is_same<
+       __boost_result_of__<functor(int const &)>::type,
+       int const &
+::value
+));
+
+// Non-class prvalue call expressions are not actually cv-qualified,
+// but only the decltype-based result_of reports this accurately.
+
+#ifdef BOOST_RESULT_OF_USE_DECLTYPE
+
+BOOST_STATIC_ASSERT((
+   boost::is_same<
+       __boost_result_of__<functor(const short)>::type,
+       short
+::value
+));
+
+#else
+
+BOOST_STATIC_ASSERT((

+[section String View]
+[/===============]
+
+[section Introduction]
+
+The class __boost_string_view__ and other classes derived from __basic_string_view__ represent references to strings or substrings. When you are parsing/processing strings from some external source, frequently you want to pass a piece of text to a procedure for specialized processing. Before __std_string_view__, the canonical way to do this used to be a __std_string__, but that has certain drawbacks:
+
+1) If you are processing a buffer of text (say a HTTP response or the contents of a file), then you have to create the string from the text you want to pass, which involves memory allocation and copying of data.
+
+2) If a routine receives a constant __std_string__ and wants to pass a portion of that string to another routine, then it must create a new string of that substring.
+
+3) If a routine receives a constant __std_string__ and wants to return a portion of the string, then it must create a new string to return.
+
+__boost_string_view__ is designed to solve these efficiency problems. A __boost_string_view__ is a read-only reference to a contiguous sequence of characters, and provides much of the functionality of __std_string__. A __boost_string_view__ is cheap to create, copy and pass by value, because it does not actually own the storage that it points to.
+
+A __boost_string_view__ is implemented as a small struct that contains a pointer to the start of the character `data` and a `count`. A __boost_string_view__ is cheap to create and cheap to copy.
+
+__boost_string_view__ acts as a container; it includes all the methods that you would expect in a container, including iteration support, `operator[]`, `at` and `size`. It can be used with any of the iterator-based algorithms in the STL - as long as you do not need to change the underlying data. For example, __std_sort__ and __std_remove__ will not work.
+
+Besides generic container functionality, __boost_string_view__ provides a subset of the interface of __std_string__. This makes it easy to replace parameters of type `const __std_string__ &` with __boost_string_view__. Like __std_string__, __boost_string_view__ has a static member variable named `npos` to denote the result of failed searches, and to mean "the end".
+
+[caution Because a __boost_string_view__ does not own the data that it refers to, it introduces lifetime issues into code that uses it. The programmer must ensure that the data that a __string_view__ refers to exists as long as the __string_view__ does.]
+
+[note
+
+Boost.Utility also includes the class __string_ref__:
+
+- __string_ref__ is the initial implementation of Jeffrey Yaskin's [@http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2012/n3442.html N3442:
+string_ref: a non-owning reference to a string].
+
+- __string_view__ is an updated implementation to reflect the Library Fundamentals TS [@http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2015/n4480.html N4480: \[string.view\]].
+
+Please prefer __string_view__ / __basic_string_view__ over __string_ref__ / __basic_string_ref__:
+
+- The __basic_string_view__ class better matches __std_basic_string_view__.
+
+- __basic_string_view__ has WAY more constexpr support.
+
+- Code that uses __basic_string_ref__ should continue to work.
+
+- Not much code depends on __basic_string_ref__ anymore.
+
+
+]
+[endsect]
+
+[/===============]
+[section Examples]
+[/===============]
+
+Integrating __string_view__ into your code is fairly simple. Wherever you pass a `const __std_string__ &` or __std_string__ as a parameter, that's a candidate for passing a __boost_string_view__.
+
+```
+__std_string__ extract_part ( const __std_string__ &bar ) {
+    return bar.substr ( 2, 3 );
+}
+
+if ( extract_part ( "ABCDEFG" ).front() == 'C' ) { /* do something */ }
+```
+
+Let's figure out what happens in this contrived example.
+
+* First, a temporary string is created from the string literal `"ABCDEFG"`, and it is passed (by reference) to the routine `extract_part`.
+* Then a second string is created in the call `__std_string__::substr` and returned to `extract_part` (this copy may be elided by RVO).
+* Then `extract_part` returns that string back to the caller (again this copy may be elided).
+* The first temporary string is deallocated, and `front` is called on the second string, and then it is deallocated as well.
+
+Two __std_string__ s are created, and two copy operations. That is potentially four memory allocations and deallocations, and the associated copying of data.
+
+Now let's look at the same code with __string_view__:
+
+```
+__boost_string_view__ extract_part ( __boost_string_view__ bar ) {
+    return bar.substr ( 2, 3 );
+}
+
+if ( extract_part ( "ABCDEFG" ).front() == "C" ) { /* do something */ }
+```
+
+No memory allocations. No copying of character data. No changes to the code other than the types. There are two __string_view__ s created, and two __string_view__ s copied, but those are cheap operations.

+[section:reference Synopsis]
+[/=================]
+
+The header file [@../../../../boost/utility/string_view.hpp `<boost/utility/string_view.hpp>`] defines a template __boost_basic_string_view__, and four specializations __string_view__, __wstring_view__, __u16string_view__, __u32string_view__ - for `char` / `wchar_t` / `char16_t` / `char32_t`.
+
+`#include <boost/utility/string_view.hpp>`
+
+Construction and copying:
+
+```
+constexpr basic_string_view ();    // Constructs an empty string_view
+constexpr basic_string_view(const charT* str); // Constructs from a NULL-terminated string
+constexpr basic_string_view(const charT* str, size_type len); // Constructs from a pointer, length pair
+template<typename Allocator>
+basic_string_view(const __std_basic_string__<charT, traits, Allocator>& str); // Constructs from a std::string
+basic_string_view (const basic_string_view &rhs);
+basic_string_view& operator=(const basic_string_view &rhs);
+```
+
+__string_view__ does not define a move constructor nor a move-assignment operator because copying a __string_view__ is just a cheap as moving one.
+
+Basic container-like functions:
+
+```
+constexpr size_type size()     const ;
+constexpr size_type length()   const ;
+constexpr size_type max_size() const ;
+constexpr bool empty()         const ;
+
+// All iterators are const_iterators
+constexpr const_iterator  begin() const ;
+constexpr const_iterator cbegin() const ;
+constexpr const_iterator    end() const ;
+constexpr const_iterator   cend() const ;
+const_reverse_iterator         rbegin() const ;
+const_reverse_iterator        crbegin() const ;
+const_reverse_iterator           rend() const ;
+const_reverse_iterator          crend() const ;
+```
+
+Access to the individual elements (all of which are const):
+
+```
+constexpr const charT& operator[](size_type pos) const ;
+const charT& at(size_t pos) const ;
+constexpr const charT& front() const ;
+constexpr const charT& back()  const ;
+constexpr const charT* data()  const ;
+```
+
+Modifying the __string_view__ (but not the underlying data):
+
+```
+void clear();
+void remove_prefix(size_type n);
+void remove_suffix(size_type n);
+```
+
+Searching:
+
+```
+size_type find(basic_string_view s) const ;
+size_type find(charT c) const ;
+size_type rfind(basic_string_view s) const ;
+size_type rfind(charT c) const ;
+size_type find_first_of(charT c) const ;

+size_type find_last_not_of(charT c) const ;
+```
+
+String-like operations:
+
+```
+constexpr basic_string_view substr(size_type pos, size_type n=npos) const ; // Creates a new string_view

+[section Value Init]
+
+[/===============]
+
+[section Introduction]
+
+Constructing and initializing objects in a generic way is difficult in
+C++. The problem is that there are several different rules that apply
+for initialization. Depending on the type, the value of a newly constructed
+object can be zero-initialized (logically 0), default-constructed (using
+the default constructor), or indeterminate. When writing generic code,
+this problem must be addressed. The template __value_initialized__ provides
+a solution with consistent syntax for value initialization of scalar,
+union and class types. Moreover, __value_initialized__ offers a workaround to various
+compiler issues regarding value-initialization.
+
+Furthermore, a `const` object __initialized_value__ is provided,
+to avoid repeating the type name when retrieving the value from a
+`__value_initialized__<T>` object.
+
+There are various ways to initialize a variable, in C++. The following
+declarations all ['may] have a local variable initialized to its default
+value:
+
+```
+T1 var1;
+T2 var2 = 0;
+T3 var3 = {};
+T4 var4 = T4();
+```
+
+Unfortunately, whether or not any of those declarations correctly
+initialize the variable very much depends on its type. The first
+declaration is valid for any __DefaultConstructible__ type by definition.
+
+However, it does not always do an initialization. It correctly initializes
+the variable when it's an instance of a class, and the author of the class
+has provided a proper default constructor. On the other hand, the value of
+`var1` is ['indeterminate] when its type is an arithmetic type, like `int`,
+`float`, or `char`.
+
+An arithmetic variable is of course initialized properly by the second declaration,
+`T2 var2 = 0`. But this initialization form will not usually work for a
+class type, unless the class was especially written to support being
+initialized that way.
+
+The third form, `T3 var3 = {}`, initializes an aggregate, typically a "C-style"
+`struct` or a "C-style" array. However, at the time this library was developed,
+the syntax did not allow for a class that has an explicitly declared constructor.
+
+The fourth form is the most generic form of them, as it can be used to initialize
+arithmetic types, class types, aggregates, pointers, and other types.
+The declaration,  `T4 var4 = T4()`, should be read as follows: First a temporary
+object is created, by `T4()`. This object is [link sec:valueinit value-initialized].
+Next the temporary object is copied to the named variable, `var4`. Afterwards,
+the temporary is destroyed. While the copying and the destruction are likely to
+be optimized away, C++ still requires the type `T4` to be __CopyConstructible__.
+So `T4` needs to be ['both] __DefaultConstructible__ ['and] __CopyConstructible__.
+
+A class may not be CopyConstructible, for example because it may have a
+private and undefined copy constructor, or because it may be derived from
+`boost::noncopyable`. Scott Meyers \[[link sec:references 2]\] explains why a
+class would be defined like that.
+
+There is another, less obvious disadvantage to the fourth form, `T4 var4 = T4()`:
+It suffers from various [link sec:compiler_issues compiler issues], causing
+a variable to be left uninitialized in some compiler specific cases.
+
+The template __value_initialized__ offers a generic way to initialize
+an object, like `T4 var4 = T4()`, but without requiring its type
+to be __CopyConstructible__. And it offers a workaround to those compiler issues
+regarding value-initialization as well. It allows getting an initialized
+variable of any type; it ['only] requires the type to be __DefaultConstructible__.
+A properly ['value-initialized] object of type `T` is constructed by the following
+declaration:
+
+```
+value_initialized<T> var;
+```
+
+The template __initialized__ offers both value-initialization and direct-initialization.
+It is especially useful as a data member type, allowing the very same object
+to be either direct-initialized or value-initialized.
+
+The `const` object __initialized_value__ allows value-initializing a variable as follows:
+
+```
+T var = initialized_value;
+```
+
+This form of initialization is semantically equivalent to `T4 var4 = T4()`,
+but robust against the aforementioned compiler issues.
+
+[endsect]
+
+[#sec:details]
+[section Details]
+
+The C++ standard \[[link sec:references 3]\] contains the definitions
+of `zero-initialization` and `default-initialization`. Informally, zero-initialization
+means that the object is given the initial value `0` converted to the type and
+default-initialization means that [@https://en.cppreference.com/w/cpp/named_req/PODType POD] \[[link sec:references 4]\] types are zero-initialized,
+while non-POD class types are initialized with their corresponding default constructors.
+
+A ['declaration] can contain an ['initializer], which specifies the
+object's initial value. The initializer can be just '()', which states that
+the object shall be value-initialized (but see below). However, if a ['declaration]
+has no ['initializer] and it is of a non-`const`, non-`static` POD type, the
+initial value is indeterminate: (see [sect]8.5, \[dcl.init\], for the
+accurate definitions).
+
+```
+int x; // no initializer. x value is indeterminate.
+__std_string__ s; // no initializer, s is default-constructed.
+
+int y = int();
+// y is initialized using copy-initialization
+// but the temporary uses an empty set of parentheses as the initializer,
+// so it is default-constructed.
+// A default constructed POD type is zero-initialized,
+// therefore, y == 0.
+
+void foo ( __std_string__ ) ;
+foo ( __std_string__() ) ;
+// the temporary string is default constructed
+// as indicated by the initializer ()
+```
+
+[#sec:valueinit]
+[h5 value-initialization]
+
+The first [@http://www.open-std.org/JTC1/SC22/WG21/docs/cwg_defects.html Technical
+Corrigendum for the C++ Standard] (TC1), whose draft was released to the public in
+November 2001, introduced [@http://www.open-std.org/JTC1/SC22/WG21/docs/cwg_defects.html#178 Core
+Issue 178], among many other issues.
+
+That issue introduced the new concept of `value-initialization`, and also fixed the
+wording for zero-initialization. Informally, value-initialization is similar to
+default-initialization with the exception that in some cases non-static data members
+and base class sub-objects are also value-initialized.
+
+The difference is that an object that is value-initialized will not have, or at least
+is less likely to have, indeterminate values for data members and base class sub-objects;
+unlike the case of an object default constructed (see Core Issue 178 for a
+normative description).
+
+In order to specify value-initialization of an object we need to use the
+empty-set initializer: `()`.
+
+As before, a declaration with no initializer specifies default-initialization,
+and a declaration with a non-empty initializer specifies copy (`=xxx`) or
+direct (`xxx`) initialization.
+
+```
+template<class T> void eat(T);
+
+int x ; // indeterminate initial value.
+
+__std_string__ s; // default-initialized.
+
+eat ( int() ) ; // value-initialized
+
+eat ( __std_string__() ) ; // value-initialized
+```
+
+[#sec:valueinitsyn]
+[h5 value-initialization syntax]
+
+Value initialization is specified using `()`. However, the empty set of
+parentheses is not permitted by the syntax of initializers because it is
+parsed as the declaration of a function taking no arguments:
+
+```
+int x() ; // declares function int(*)()
+```
+
+Thus, the empty `()` must be put in some other initialization context.
+
+One alternative is to use copy-initialization syntax:
+
+```
+int x = int();
+```
+
+This works perfectly fine for POD types. But for non-POD class types,
+copy-initialization searches for a suitable constructor, which could be,
+for instance, the copy-constructor. It also searches for a suitable conversion
+sequence but this does not apply in this context.
+
+For an arbitrary unknown type, using this syntax may not have the
+value-initialization effect intended because we don't know if a copy
+from a default constructed object is exactly the same as a default
+constructed object, and the compiler is allowed, in
+some cases, but never required to, optimize the copy away.
+
+One possible generic solution is to use value-initialization of a non static
+data member:
+
+```
+template<class T>
+struct W
+{
+    // value-initialization of 'data' here.
+    W() : data() {}
+
+    T data;
+};
+
+W<int> w;
+// w.data is value-initialized for any type.
+```
+
+This is the solution as it was supplied by earlier versions of the
+`__value_initialized__<T>` template class. Unfortunately this approach
+suffered from various compiler issues.
+
+[#sec:compiler_issues]
+[h5 Compiler issues]
+
+Various compilers have not yet fully implemented value-initialization.
+So when an object should be ['value-initialized] according to the C++ Standard,
+it ['may] in practice still be left uninitialized, because of those
+compiler issues. It is hard to make a general statement on what those issues
+are like, because they depend on the compiler you are using, its version number,
+and the type of object you would like to have value-initialized.
+
+All compilers we have tested so far support value-initialization for arithmetic types properly.
+However, various compilers may leave some types of ['aggregates] uninitialized, when they
+should be value-initialized. Value-initialization of objects of a pointer-to-member type may also
+go wrong on various compilers.
+
+At the moment of writing, May 2010, the following reported issues regarding
+value-initialization are still there in current compiler releases:
+
+
+
+* [@https://connect.microsoft.com/VisualStudio/feedback/details/100744 Microsoft Visual Studio Feedback ID 100744, Value-initialization in new-expression]: Reported by Pavel Kuznetsov (MetaCommunications Engineering), 2005.

+
+Note that all known GCC issues regarding value-initialization are fixed with GCC version 4.4, including
+[@http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30111 GCC Bug 30111]. Clang also has completely implemented
+value-initialization, as far as we know, now that [@http://llvm.org/bugs/show_bug.cgi?id=7139 Clang Bug 7139]
+is fixed.
+
+New versions of __value_initialized__ (Boost release version 1.35 or higher) offer a workaround to these
+issues: __value_initialized__ may now clear its internal data, prior to constructing the object that it
+contains. It will do so for those compilers that need to have such a workaround, based on the

+compiler defect macro] `BOOST_NO_COMPLETE_VALUE_INITIALIZATION`.

+
+An object of this template class is a `T`-wrapper convertible to `'T&'` whose
+wrapped object (data member of type `T`) is [link sec:valueinit value-initialized] upon default-initialization
+of this wrapper class:
+
+```
+int zero = 0;
+__value_initialized__<int> x;
+assert( x == zero ) ;
+
+__std_string__ def;
+__value_initialized__< __std_string__ > y;
+assert( y == def ) ;
+```
+
+The purpose of this wrapper is to provide a consistent syntax for value initialization
+of scalar, union and class types (POD and non-POD) since the correct syntax for value
+initialization varies (see [link sec:valueinitsyn value-initialization syntax]).
+
+The wrapped object can be accessed either through the conversion operator
+`T&`, the member function `data()`, or the non-member function `get()`:
+
+```
+void watch(int);
+
+__value_initialized__<int> x;
+
+watch(x) ; // operator T& used.
+watch(x.data());
+watch( get(x) ) // function get() used
+```
+
+Both `const` and non-`const` objects can be wrapped. Mutable objects can be
+modified directly from within the wrapper but constant objects cannot:
+
+When `T` is a __Swappable__ type, `__value_initialized__<T>`
+is swappable as well, by calling its `swap` member function
+as well as by calling `boost::swap`.
+
+```
+__value_initialized__<int> x;
+static_cast<int&>(x) = 1 ; // OK
+get(x) = 1 ; // OK
+
+__value_initialized__<int const> y ;
+static_cast<int&>(y) = 1 ; // ERROR: cannot cast to int&
+static_cast<int const&>(y) = 1 ; // ERROR: cannot modify a const value
+get(y) = 1 ; // ERROR: cannot modify a const value
+```
+
+[warning
+
+The __value_initialized__ implementation of Boost version 1.40.0 and older
+allowed ['non-const] access to the wrapped object, from a constant wrapper,
+both by its conversion operator and its `data()` member function.
+
+For example:
+
+```
+__value_initialized__<int> const x_c;
+int& xr = x_c ; // OK, conversion to int& available even though x_c is itself const.
+xr = 2 ;
+```
+
+The reason for this obscure behavior was that some compilers did not accept the following valid code:
+
+```
+struct X
+{
+  operator int&() ;
+    operator int const&() const ;
+  };
+  X x ;
+  (x == 1) ; // ERROR HERE!
+```
+
+The current version of __value_initialized__ no longer has this obscure behavior.
+As compilers nowadays widely support overloading the conversion operator by having a `const`
+and a `non-const` version, we have decided to fix the issue accordingly. So the current version
+supports the idea of logical constness.
+
+]
+
+[h5 Recommended practice: The non-member get() idiom]
+
+The obscure behavior of being able to modify a non-`const`
+wrapped object from within a constant wrapper (as was supported by previous
+versions of __value_initialized__) can be avoided if access to the wrapped object
+is always performed with the `get()` idiom:
+
+```

+
+The template class `boost::__initialized__<T>` supports both value-initialization
+and direct-initialization, so its interface is a superset of the interface
+of `__value_initialized__<T>`: Its default-constructor value-initializes the
+wrapped object just like the default-constructor of `__value_initialized__<T>`,
+but `boost::__initialized__<T>` also offers an extra `explicit`
+constructor, which direct-initializes the wrapped object by the specified value.
+
+`__initialized__<T>` is especially useful when the wrapped
+object must be either value-initialized or direct-initialized, depending on
+runtime conditions. For example, `__initialized__<T>` could
+hold the value of a data member that may be value-initialized by some
+constructors, and direct-initialized by others.
+
+On the other hand, if it is known beforehand that the
+object must ['always] be value-initialized, `__value_initialized__<T>`
+may be preferable. And if the object must always be
+direct-initialized, none of the two wrappers really needs to be used.

+T var = T();
+```
+
+But as mentioned before, this form suffers from various compiler issues.
+The template __value_initialized__ offers a workaround:
+
+```
+T var = get( __value_initialized__<T>() );
+```
+
+Unfortunately both forms repeat the type name, which
+is rather short now (`T`), but could of course be
+more like `Namespace::Template<Arg>::Type`.
+
+Instead, one could use __initialized_value__ as follows:
+
+```
+T var = __initialized_value__;
+```

-<h1>Filter Iterator Adaptor</h1>
-
-Defined in header
-<a href="../../boost/iterator_adaptors.hpp">boost/iterator_adaptors.hpp</a>
-
-
-<p>
-The filter iterator adaptor creates a view of an iterator range in
-which some elements of the range are skipped over. A <a
-href="http://www.sgi.com/tech/stl/Predicate.html">Predicate</a>
-function object controls which elements are skipped. When the
-predicate is applied to an element, if it returns <tt>true</tt> then
-the element is retained and if it returns <tt>false</tt> then the
-element is skipped over.
-
-
-<h2>Synopsis</h2>
-
-<pre>
-namespace boost {
-  template &lt;class Predicate, class BaseIterator, ...&gt;
-  class filter_iterator_generator;
-
-  template &lt;class Predicate, class BaseIterator&gt;

-<h2><a name="filter_iterator_generator">The Filter Iterator Type
-Generator</a></h2>
-
-The class <tt>filter_iterator_generator</tt> is a helper class whose
-purpose is to construct a filter iterator type.  The template
-parameters for this class are the <tt>Predicate</tt> function object
-type and the <tt>BaseIterator</tt> type that is being wrapped.  In
-most cases the associated types for the wrapped iterator can be
-deduced from <tt>std::iterator_traits</tt>, but in some situations the
-user may want to override these types, so there are also template
-parameters for each of the iterator's associated types.
-
-<pre>
-template &lt;class Predicate, class BaseIterator,
-          class Value, class Reference, class Pointer, class Category, class Distance>
-class filter_iterator_generator
-{
-public:
-  typedef <tt><a href="./iterator_adaptors.htm#iterator_adaptor">iterator_adaptor</a>&lt...&gt;</tt> type; // the resulting filter iterator type 
-}
-</pre>
-
-
-<h3>Example</h3>
-
-The following example uses filter iterator to print out all the
-positive integers in an array. 
-
-<pre>
-struct is_positive_number {
-  bool operator()(int x) { return 0 &lt; x; }
-};
-int main() {

-  const int N = sizeof(numbers)/sizeof(int);
-
-  typedef boost::filter_iterator_generator&lt;is_positive_number, int*, int&gt;::type FilterIter;
-  is_positive_number predicate;
-  FilterIter::policies_type policies(predicate, numbers + N);
-  FilterIter filter_iter_first(numbers, policies);
-  FilterIter filter_iter_last(numbers + N, policies);
-
-  std::copy(filter_iter_first, filter_iter_last, std::ostream_iterator&lt;int&gt;(std::cout, " "));
-  std::cout &lt;&lt; std::endl;

-The filter iterator adaptor (the type
-<tt>filter_iterator_generator<...>::type</tt>) may be a model of <a
-href="http://www.sgi.com/tech/stl/InputIterator.html">InputIterator</a> or <a

-<h3>Members</h3>
-
-The filter iterator type implements all of the member functions and
-operators required of the <a

-
-<pre>filter_iterator_generator::type(const BaseIterator& it, const Policies& p = Policies())</pre>
-
-<p>
-The policies type has only one public function, which is its constructor:

-	    std::ostream_iterator<int>(std::cout, " "));
-  std::cout << std::endl;
-
-}
-</pre>
-The output is:

-<h3>Notes</h3>
-
-<a name="1">[1]</a> If the compiler does not support partial

-the <tt>Value</tt> type must be explicitly specified (don't use the
-default).

-    Defined in header <a href=
-    "../../boost/function_output_iterator.hpp">boost/function_output_iterator.hpp</a> 
-
-    <p>The function output iterator adaptor makes it easier to create
-    custom output iterators. The adaptor takes a <a
-    href="http://www.sgi.com/tech/stl/UnaryFunction.html">Unary
-    Function</a> and creates a model of <a
-    href="http://www.sgi.com/tech/stl/OutputIterator.html">Output
-    Iterator</a>. Each item assigned to the output iterator is passed
-    as an argument to the unary function.  The motivation for this
-    iterator is that creating a C++ Standard conforming output
-    iterator is non-trivial, particularly because the proper
-    implementation usually requires a proxy object. On the other hand,
-    creating a function (or function object) is much simpler.

+</pre><p>
+    </p><p>
+      The first macro invocation works correctly declaring a variable named <code class="computeroutput"><span class="identifier">var1</span></code> of type <code class="computeroutput"><span class="keyword">int</span></code>.
+      However, the second macro invocation fails generating a preprocessor error
+      similar to the following:
+    </p><pre class="programlisting">error: macro "VAR" passed 3 arguments, but takes just 2
+</pre><p>
+      That is because the <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">map</span></code> type passed as the first macro parameter
+      contains a comma <code class="computeroutput"><span class="special">,</span></code> not wrapped
+      by round parenthesis <code class="computeroutput"><span class="special">()</span></code>. The preprocessor
+      interprets that unwrapped comma as a separation between macro parameters concluding
+      that a total of three (and not two) parameters are passed to the macro in the
+      following order:
+    </p><div class="orderedlist"><ol class="orderedlist" type="1"><li class="listitem">
+          <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">map</span><span class="special">&lt;</span><span class="keyword">int</span></code>

+        </li><li class="listitem">
+          <code class="computeroutput"><span class="number">2</span></code>
+        </li></ol></div><p>
+      Note that, differently from the compiler, the preprocessor only recognizes
+      round parenthesis <code class="computeroutput"><span class="special">()</span></code>. Angular
+      <code class="computeroutput"><span class="special">&lt;&gt;</span></code> and squared <code class="computeroutput"><span class="special">[]</span></code> parenthesis are not recognized by the preprocessor
+      when parsing macro parameters.
+    </p></div><div class="section boost_utility_identitytype_solution" title="Solution"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="boost_utility_identitytype.solution"></a><a class="link" href="#boost_utility_identitytype.solution" title="Solution">Solution</a></h2></div></div></div><p>
+      In some cases, it might be possible to workaround this issue by avoiding to
+      pass the type expression to the macro all together. For example, in the case
+      above a <code class="computeroutput"><span class="keyword">typedef</span></code> could have been
+      used to specify the type expression with the commas outside the macro (see
+      also <a href="../../test/var.cpp" target="_top"><code class="literal">var.cpp</code></a>):

+<span class="identifier">VAR</span><span class="special">(</span><span class="identifier">map_type</span><span class="special">,</span> <span class="number">3</span><span class="special">);</span> <span class="comment">// OK.</span>
+</pre><p>
+    </p><p>

+    [authors [Caminiti <email>lorcaminiti@gmail.com</email>, Lorenzo]]
+    [category Utilities]
+]
+
+This library allows to wrap types within round parenthesis so they can always be passed as macro parameters.
+
+[import ../test/var_error.cpp]
+[import ../test/var.cpp]
+[import ../test/template.cpp]
+[import ../test/abstract.cpp]
+[import ../test/paren.cpp]
+
+[section Motivation]
+
+Consider the following macro which declares a variable named `var`[^['n]] with the specified [^['type]] (see also [@../../test/var_error.cpp =var_error.cpp=]):
+
+[var_error]
+
+The first macro invocation works correctly declaring a variable named `var1` of type `int`.
+However, the second macro invocation fails generating a preprocessor error similar to the following:
+
+[pre
+    error: macro "VAR" passed 3 arguments, but takes just 2
+]
+
+That is because the `std::map` type passed as the first macro parameter contains a comma `,` not wrapped by round parenthesis `()`.
+The preprocessor interprets that unwrapped comma as a separation between macro parameters concluding that a total of three (and not two) parameters are passed to the macro in the following order:
+
+# `std::map<int`
+# `char>`
+# `2`
+
+Note that, differently from the compiler, the preprocessor only recognizes round parenthesis `()`.
+Angular `<>` and squared `[]` parenthesis are not recognized by the preprocessor when parsing macro parameters.
+
+[endsect]
+
+[section Solution]
+
+In some cases, it might be possible to workaround this issue by avoiding to pass the type expression to the macro all together.
+For example, in the case above a `typedef` could have been used to specify the type expression with the commas outside the macro (see also [@../../test/var.cpp =var.cpp=]):
+
+[var_typedef]
+
+When this is neither possible nor desired (e.g., see the function template `f` in the section below), this library header [headerref boost/utility/identity_type.hpp] defines a macro [macroref BOOST_IDENTITY_TYPE] which can be used to workaround the issue while keeping the type expression as one of the macro parameters (see also [@../../test/var.cpp =var.cpp=]).
+
+[var_ok]
+
+The [macroref BOOST_IDENTITY_TYPE] macro expands to an expression that evaluates (at compile-time) to the specified type.
+The specified type is never split into multiple macro parameters because it is always wrapped by a set of extra round parenthesis `()`.
+In fact, a total of two sets of round parenthesis must be used: The parenthesis to invoke the macro `BOOST_IDENTITY_TYPE(...)` plus the inner parenthesis to wrap the type passed to the macro `BOOST_IDENTITY_TYPE((...))`.
+
+This macro works on any [@http://www.open-std.org/JTC1/SC22/WG21/docs/standards C++03] compiler (and it does not use [@http://en.wikipedia.org/wiki/Variadic_macro variadic macros]).
+[footnote
+Using variadic macros, it would be possible to require a single set of extra parenthesis `BOOST_IDENTITY_TYPE(`[^['type]]`)` instead of two `BOOST_IDENTITY_TYPE((`[^['type]]`))` but variadic macros are not part of C++03 (even if nowadays they are supported by most modern compilers and they are also part of C++11).
+]
+The authors originally developed and tested this library using GNU Compiler Collection (GCC) C++ 4.5.3 (with and without C++11 features enabled `-std=c++0x`) on Cygwin and Miscrosoft Visual C++ (MSVC) 8.0 on Windows 7.
+See the library [@http://www.boost.org/development/tests/release/developer/utility-identity_type.html regressions test results] for more information on supported compilers and platforms.
+
+[endsect]
+
+[section Templates]
+
+This macro must be prefixed by `typename` when used within templates.
+For example, let's program a macro that declares a function parameter named `arg`[^['n]] with the specified [^['type]] (see also [@../../test/template.cpp =template.cpp=]):
+
+[template_f_decl]
+[template_f_call]
+
+However, note that the template parameter `char` must be manually specified when invoking the function as in `f<char>(a)`.
+In fact, when the [macroref BOOST_IDENTITY_TYPE] macro is used to wrap a function template parameter, the template parameter can no longer be automatically deduced by the compiler form the function call as `f(a)` would have done.
+[footnote
+This is because the implementation of [macroref BOOST_IDENTITY_TYPE] wraps the specified type within a meta-function.
+]
+(This limitation does not apply to class templates because class template parameters must always be explicitly specified.)
+In other words, without using the [macroref BOOST_IDENTITY_TYPE] macro, C++ would normally be able to automatically deduce the function template parameter as shown below:
+
+[template_g_decl]
+[template_g_call]
+
+[endsect]
+
+[section Abstract Types]
+
+On some compilers (e.g., GCC), using this macro on abstract types (i.e., classes with one or more pure virtual functions) generates a compiler error.
+This can be avoided by manipulating the type adding and removing a reference to it.
+
+Let's program a macro that performs a static assertion on a [@http://en.wikipedia.org/wiki/Template_metaprogramming Template Meta-Programming] (TMP) meta-function (similarly to Boost.MPL [@http://www.boost.org/doc/libs/1_36_0/libs/mpl/doc/refmanual/assert.html `BOOST_MPL_ASSERT`]).
+The [macroref BOOST_IDENTITY_TYPE] macro can be used to pass a meta-function with multiple template parameters to the assert macro (so to handle the commas separating the template parameters).
+In this case, if the meta-function is an abstract type, it needs to be manipulated adding and removing a reference to it (see also [@../../test/abstract.cpp =abstract.cpp=]):
+
+[abstract]
+
+[endsect]
+
+[section Annex: Usage]
+
+The [macroref BOOST_IDENTITY_TYPE] macro can be used either when calling a user-defined macro (as shown by the examples so far), or internally when implementing a user-defined macro (as shown below).
+When [macroref BOOST_IDENTITY_TYPE] is used in the implementation of the user-defined macro, the caller of the user macro will have to specify the extra parenthesis (see also [@../../test/paren.cpp =paren.cpp=]):
+
+[paren]
+
+However, note that the caller will /always/ have to specify the extra parenthesis even when the macro parameters contain no comma:
+
+[paren_always]
+
+In some cases, using [macroref BOOST_IDENTITY_TYPE] in the implementation of the user-defined macro might provide the best syntax for the caller.
+For example, this is the case for `BOOST_MPL_ASSERT` because the majority of template meta-programming expressions contain unwrapped commas so it is less confusing for the user to always specify the extra parenthesis `((...))` instead of using [macroref BOOST_IDENTITY_TYPE]:
+
+    BOOST_MPL_ASSERT(( // Natural syntax.
+        boost::mpl::and_<
+              boost::is_const<T>
+            , boost::is_reference<T>
+        >
+    ));
+
+However, in other situations it might be preferable to not require the extra parenthesis in the common cases and handle commas as special cases using [macroref BOOST_IDENTITY_TYPE].
+For example, this is the case for [@http://www.boost.org/libs/local_function `BOOST_LOCAL_FUNCTION`] for which always requiring the extra parenthesis `((...))` around the types would lead to an unnatural syntax for the local function signature:
+
+    int BOOST_LOCAL_FUNCTION( ((int&)) x, ((int&)) y ) { // Unnatural syntax.
+        return x + y;
+    } BOOST_LOCAL_FUNCTION_NAME(add)
+
+Instead requiring the user to specify [macroref BOOST_IDENTITY_TYPE] only when needed allows for the more natural syntax `BOOST_LOCAL_FUNCTION(int& x, int& y)` in the common cases when the parameter types contain no comma (while still allowing to specify parameter types with commas as special cases using `BOOST_LOCAL_FUNCTION(BOOST_IDENTITY_TYPE((std::map<int, char>))& x, int& y)`).
+
+[endsect]
+
+[section Annex: Implementation]
+
+The implementation of this library macro is equivalent to the following:
+[footnote
+There is absolutely no guarantee that the macro is actually implemented using the code listed in this documentation.
+The listed code is for explanatory purposes only.
+]
+
+    #include <boost/type_traits/function_traits.hpp>
+    
+    #define BOOST_IDENTITY_TYPE(parenthesized_type) \
+        boost::function_traits<void parenthesized_type>::arg1_type
+
+Essentially, the type is wrapped between round parenthesis `(std::map<int, char>)` so it can be passed as a single macro parameter even if it contains commas.
+Then the parenthesized type is transformed into the type of a function returning `void` and with the specified type as the type of the first and only argument `void (std::map<int, char>)`.
+Finally, the type of the first argument `arg1_type` is extracted at compile-time using the `function_traits` meta-function therefore obtaining the original type from the parenthesized type (effectively stripping the extra parenthesis from around the specified type).

+//  24 May 07 Changed empty_base to depend on T, see
+//            http://svn.boost.org/trac/boost/ticket/979
+//  21 Oct 02 Modified implementation of operators to allow compilers with a
+//            correct named return value optimization (NRVO) to produce optimal
+//            code.  (Daniel Frey)
+//  02 Dec 01 Bug fixed in random_access_iteratable.  (Helmut Zeisel)
+//  28 Sep 01 Factored out iterator operator groups.  (Daryle Walker)
+//  27 Aug 01 'left' form for non commutative operators added;
+//            additional classes for groups of related operators added;
+//            workaround for empty base class optimization
+//            bug of GCC 3.0 (Helmut Zeisel)
+//  25 Jun 01 output_iterator_helper changes: removed default template

+//            documentation and tests (Aleksey Gurtovoy)
+//  29 May 01 Added operator classes for << and >>.  Added input and output
+//            iterator helper classes.  Added classes to connect equality and
+//            relational operators.  Added classes for groups of related
+//            operators.  Reimplemented example operator and iterator helper
+//            classes in terms of the new groups.  (Daryle Walker, with help
+//            from Alexy Gurtovoy)
+//  11 Feb 01 Fixed bugs in the iterator helpers which prevented explicitly

+//  12 Dec 99 Initial version with iterator operators (Jeremy Siek)

+//            specializations of dividable, subtractable, modable (Ed Brey) 
+//  17 Nov 99 Add comments (Beman Dawes)
+//            Remove unnecessary specialization of operators<> (Ed Brey)
+//  15 Nov 99 Fix less_than_comparable<T,U> second operand type for first two
+//            operators.(Beman Dawes)
+//  12 Nov 99 Add operators templates (Ed Brey)
+//  11 Nov 99 Add single template parameter version for compilers without
+//            partial specialization (Beman Dawes)
+//  10 Nov 99 Initial version
+
+// 10 Jun 00:
+// An additional optional template parameter was added to most of 
+// operator templates to support the base class chaining technique (see 
+// documentation for the details). Unfortunately, a straightforward
+// implementation of this change would have broken compatibility with the
+// previous version of the library by making it impossible to use the same
+// template name (e.g. 'addable') for both the 1- and 2-argument versions of
+// an operator template. This implementation solves the backward-compatibility
+// issue at the cost of some simplicity.
+//
+// One of the complications is an existence of special auxiliary class template
+// 'is_chained_base<>' (see 'detail' namespace below), which is used
+// to determine whether its template parameter is a library's operator template
+// or not. You have to specialize 'is_chained_base<>' for each new 
+// operator template you add to the library.
+//
+// However, most of the non-trivial implementation details are hidden behind 
+// several local macros defined below, and as soon as you understand them,
+// you understand the whole library implementation.

+    The following code works by converting the input bit pattern into a
+    Boost.Preprocessor sequence, then converting groupings of 3 bits each into
+    the corresponding octal digit, and finally concatenating all of the digits
+    together along with a leading zero. This yields a standard octal literal
+    with the desired value as specified in bits.

+
+This macro works on any C++03 compiler (it does not use variadic macros).
+
+This macro must be prefixed by <c>typename</c> when used within templates.
+Note that the compiler will not be able to automatically determine function
+template parameters when they are wrapped with this macro (these parameters
+need to be explicitly specified when calling the function template).
+
+On some compilers (like GCC), using this macro on abstract types requires to
+add and remove a reference to the specified type.

-    <h1>Indirect Iterator Adaptor</h1>
-    Defined in header <a href=
-    "../../boost/iterator_adaptors.hpp">boost/iterator_adaptors.hpp</a> 
-
-    <p>The indirect iterator adaptor augments an iterator by applying an
-    <b>extra</b> dereference inside of <tt>operator*()</tt>. For example, this
-    iterator makes it possible to view a container of pointers or
-    smart-pointers (e.g. <tt>std::list&lt;boost::shared_ptr&lt;foo&gt;
-    &gt;</tt>) as if it were a container of the pointed-to type. The following
-    <b>pseudo-code</b> shows the basic idea of the indirect iterator:
-
-    <blockquote>
-<pre>
-// inside a hypothetical indirect_iterator class...
-typedef std::iterator_traits&lt;BaseIterator&gt;::value_type Pointer;
-typedef std::iterator_traits&lt;Pointer&gt;::reference reference;
-
-reference indirect_iterator::operator*() const {
-  return **this-&gt;base_iterator;
-}
-</pre>
-    </blockquote>
-
-    <h2>Synopsis</h2>
-

-    <h2><a name="indirect_iterator_generator">The Indirect Iterator Type
-    Generator</a></h2>
-    The <tt>indirect_iterator_generator</tt> template is a <a href=
-    "../../more/generic_programming.html#type_generator">generator</a> of
-    indirect iterator types. The main template parameter for this class is the
-    <tt>BaseIterator</tt> type that is being wrapped. In most cases the type of
-    the elements being pointed to can be deduced using
-    <tt>std::iterator_traits</tt>, but in some situations the user may want to
-    override this type, so there are also template parameters that allow a user
-    to control the <tt>value_type</tt>, <tt>pointer</tt>, and
-    <tt>reference</tt> types of the resulting iterators. 
-
-    <blockquote>
-<pre>
-template &lt;class BaseIterator,
-          class Value, class Reference, class Pointer&gt;
-class indirect_iterator_generator

-};
-</pre>
-    </blockquote>
-
-    <h3>Example</h3>
-    This example uses the <tt>indirect_iterator_generator</tt> to create
-    indirect iterators which dereference the pointers stored in the
-    <tt>pointers_to_chars</tt> array to access the <tt>char</tt>s in the
-    <tt>characters</tt> array.

-    <h3>Concept Model</h3>
-    The indirect iterator will model whichever <a href=
-    "http://www.sgi.com/tech/stl/Iterators.html">standard iterator
-    concept category</a> is modeled by the base iterator. Thus, if the
-    base iterator is a model of <a href=
-    "http://www.sgi.com/tech/stl/RandomAccessIterator.html">Random
-    Access Iterator</a> then so is the resulting indirect iterator. If
-    the base iterator models a more restrictive concept, the resulting
-    indirect iterator will model the same concept <a href="#3">[3]</a>.
-
-    <h3>Members</h3>
-    The indirect iterator type implements the member functions and operators
-    required of the <a href=
-    "http://www.sgi.com/tech/stl/RandomAccessIterator.html">Random Access
-    Iterator</a> concept. In addition it has the following constructor: 
-<pre>
-explicit indirect_iterator_generator::type(const BaseIterator&amp; it)

-    Generator</a></h2>
-    Sometimes a pair of <tt>const</tt>/non-<tt>const</tt> pair of iterators is
-    needed, such as when implementing a container. The
-    <tt>indirect_iterator_pair_generator</tt> class makes it more convenient to
-    create this pair of iterator types.

-    <h3>Concept Model</h3>
-
-    The indirect iterators will model whichever <a href=
-    "http://www.sgi.com/tech/stl/Iterators.html">standard iterator
-    concept category</a> is modeled by the base iterator. Thus, if the
-    base iterator is a model of <a href=
-    "http://www.sgi.com/tech/stl/RandomAccessIterator.html">Random
-    Access Iterator</a> then so are the resulting indirect
-    iterators. If the base iterator models a more restrictive concept,
-    the resulting indirect iterators will model the same concept <a
-    href="#3">[3]</a>.
-
-
-    <h3>Members</h3>
-    The resulting <tt>iterator</tt> and <tt>const_iterator</tt> types implement
-    the member functions and operators required of the <a href=
-    "http://www.sgi.com/tech/stl/RandomAccessIterator.html">Random Access
-    Iterator</a> concept. In addition they support the following constructors: 
-
-    <blockquote>
-<pre>
-explicit indirect_iterator_pair_generator::iterator(const BaseIterator&amp; it)
-explicit indirect_iterator_pair_generator::const_iterator(const BaseIterator&amp; it)
-</pre>
-    </blockquote>
-    <br>
-     <br>
-     
-    <hr>
-
-    <p>
-
-    <h2><a name="make_indirect_iterator">The Indirect Iterator Object
-    Generator</a></h2>
-    The <tt>make_indirect_iterator()</tt> function provides a more convenient
-    way to create indirect iterator objects. The function saves the user the
-    trouble of explicitly writing out the iterator types. 
-
-    <blockquote>
-<pre>
-template &lt;class BaseIterator&gt;
-typename indirect_iterator_generator&lt;BaseIterator&gt;::type
-make_indirect_iterator(BaseIterator base)  
-</pre>
-    </blockquote>
-
-    <h3>Example</h3>
-    Here we again print the <tt>char</tt>s from the array <tt>characters</tt>
-    by accessing them through the array of pointers <tt>pointer_to_chars</tt>,
-    but this time we use the <tt>make_indirect_iterator()</tt> function which
-    saves us some typing. 
-
-    <blockquote>
-<pre>
-  // continuing from the last example...
-
-  std::copy(boost::make_indirect_iterator(pointers_to_chars), 
-      boost::make_indirect_iterator(pointers_to_chars + N),
-      std::ostream_iterator&lt;char&gt;(std::cout, ","));
-  std::cout &lt;&lt; std::endl;
-
-  return 0;
-}
-</pre>
-    </blockquote>
-    The output is: 
-
-    <blockquote>
-<pre>
-a,b,c,d,e,f,g,
-</pre>
-    </blockquote>
-    <hr>
-
-    <h3>Notes</h3>
-
-    <p>
-
-    <p><a name="2">[2]</a> If your compiler does not support partial
-    specialization and the base iterator or its <tt>value_type</tt> is a
-    builtin pointer type, you will not be able to use the default for
-    <tt>Value</tt> and will need to specify this type explicitly.
-
-    <p><a name="3">[3]</a>There is a caveat to which concept the
-    indirect iterator can model.  If the return type of the
-    <tt>operator*</tt> for the base iterator's value type is not a
-    true reference, then strickly speaking, the indirect iterator can
-    not be a model of <a href=
-    "http://www.sgi.com/tech/stl/ForwardIterator.html">Forward
-    Iterator</a> or any of the concepts that refine it. In this case
-    the <tt>Category</tt> for the indirect iterator should be
-    specified as <tt>std::input_iterator_tag</tt>. However, even in
-    this case, if the base iterator is a random access iterator, the
-    resulting indirect iterator will still satisfy most of the
-    requirements for <a href=
-    "http://www.sgi.com/tech/stl/RandomAccessIterator.html">Random
-    Access Iterator</a>.

-    <h1>Boost Iterator Adaptor Library</h1>
-
-    <h2>Introduction</h2>
-
-    <p>The Iterator Adaptor library allows you transform an arbitrary ``base''
-    type into a standard-conforming iterator with the behaviors you choose.
-    Doing so is especially easy if the ``base'' type is itself an iterator. The
-    library also supplies several example <a href=
-    "../../more/generic_programming.html#adaptors">adaptors</a> which apply
-    specific useful behaviors to arbitrary base iterators.

-    Implementing standard conforming iterators is a non-trivial task. There are
-    some fine points such as the interactions between an iterator and its
-    corresponding const_iterator, and there are myriad operators that should be
-    implemented but are easily forgotten or mishandled, such as
-    <tt>operator-&gt;()</tt>. Using <tt>iterator_adaptor</tt>, you can easily
-    implement an iterator class, and even more easily extend and <a href=
-    "../../more/generic_programming.html#adaptors">adapt</a> existing iterator
-    types. Moreover, it is easy to make a pair of interoperable <tt>const</tt>
-    and <tt>non-const</tt> iterators. 
-
-    <p><tt>iterator_adaptor</tt> is declared like this:
-<pre>

-    fifth. As a solution to these problems we provide a mechanism for
-    naming the last five template parameters, and providing them in
-    any order through the <tt>iterator_traits_generator</tt> class.
-
-    <blockquote>
-<pre>
-<a name="iterator_traits_generator">class iterator_traits_generator</a>
-{
-public:
-  template &lt;class Value&gt;
-  struct value_type : public <i>recursive magic</i> { };
-
-  template &lt;class Reference&gt;
-  struct reference : public <i>recursive magic</i> { };
-
-  template &lt;class Pointer&gt;
-  struct pointer : public <i>recursive magic</i> { };
-
-  template &lt;class Distance&gt;
-  struct difference_type : public <i>recursive magic</i> { };
-
-  template &lt;class Category&gt;
-  struct iterator_category : public <i>recursive magic</i> { };
-};
-</pre>
-    </blockquote>
-
-    The <tt>iterator_traits_generator</tt> is used to create a list of
-    of template arguments. For example, suppose you want to set the
-    <tt>Reference</tt> and <tt>Category</tt> parameters, and use the
-    defaults for the rest. Then you can use the traits generator as
-    follows:
-
-    <blockquote>
-<pre>
-iterator_traits_generator::reference&lt;foo&gt;::category&lt;std::input_iterator_tag&gt;
-</pre>
-    </blockquote>
-
-    This generated type can then be passed into the <tt>iterator_adaptor</tt>
-    class to replace any of the last five parameters. If you use the traits
-    generator in the <i>i</i>th parameter position, then the parameters <i>i</i>
-    through 7 will use the types specified in the generator. For example, the
-    following adapts <tt>foo_iterator</tt> to create an <a href=
-    "http://www.sgi.com/tech/stl/InputIterator.html">InputIterator</a> with
-    <tt>reference</tt> type <tt>foo</tt>, and whose other traits are determined
-    according to the defaults described <a href="#template_parameters">above</a>.
-
-    <blockquote>
-<pre>
-iterator_adaptor&lt;foo_iterator, foo_policies,

-    <h3><a name="example">Example</a></h3>
-
-    <p>It is often useful to automatically apply some function to the value
-    returned by dereferencing an iterator. The <a href=
-    "./transform_iterator.htm">transform iterator</a> makes it easy to create
-    an iterator adaptor which does just that. Here we will show how easy it is
-    to implement the transform iterator using the <tt>iterator_adaptor</tt>
-    template.
-
-    <p>We want to be able to adapt a range of iterators and functions, so the
-    policies class will have a template parameter for the function type and it
-    will have a data member of that type. We know that the function takes one
-    argument and that we'll need to be able to deduce the <tt>result_type</tt>
-    of the function so we can use it for the adapted iterator's
-    <tt>value_type</tt>. <a href=
-    "http://www.sgi.com/Technology/STL/AdaptableUnaryFunction.html">AdaptableUnaryFunction</a>
-    is the <a href="../../more/generic_programming.html#concept">Concept</a>
-    that fulfills those requirements.
-
-    <p>To implement a transform iterator we will only change one of the base
-    iterator's behaviors, so the <tt>transform_iterator_policies</tt> class can
-    inherit the rest from <tt>default_iterator_policies</tt>. We will define
-    the <tt>dereference()</tt> member function, which is used to implement
-    <tt>operator*()</tt> of the adapted iterator. The implementation will
-    dereference the base iterator and apply the function object. The
-    <tt>type&lt;Reference&gt;</tt> parameter is used to convey the appropriate
-    return type. The complete code for <tt>transform_iterator_policies</tt>
-    is:<br>
-    <br>
-
-
-    <blockquote>
-<pre>
-  template &lt;class AdaptableUnaryFunction&gt;
-  struct transform_iterator_policies : public default_iterator_policies
-  {
-    transform_iterator_policies() { }
-
-    transform_iterator_policies(const AdaptableUnaryFunction&amp; f)
-      : m_f(f) { }
-
-    template &lt;class Reference, class BaseIterator&gt;
-    Reference dereference(type&lt;Reference&gt;, const BaseIterator&amp; i) const
-      { return m_f(*i); }
-
-    AdaptableUnaryFunction m_f;
-  };
-</pre>
-    </blockquote>
-
-    <p>The next step is to use the <tt>iterator_adaptor</tt> template to
-    construct the transform iterator type. The nicest way to package the
-    construction of the transform iterator is to create a <a href=
-    "../../more/generic_programming.html#type_generator">type generator</a>.
-    The first template parameter to the generator will be the type of the
-    function object and the second will be the base iterator type. We use
-    <tt>iterator_adaptor</tt> to define the transform iterator type as a nested
-    <tt>typedef</tt> inside the <tt>transform_iterator_generator</tt> class.
-    Because the function may return by-value, we must limit the
-    <tt>iterator_category</tt> to <a href=
-    "http://www.sgi.com/tech/stl/InputIterator.html">Input Iterator</a>, and
-    the iterator's <tt>reference</tt> type cannot be a true reference (the
-    standard allows this for input iterators), so in this case we can use few
-    of <tt>iterator_adaptor</tt>'s default template arguments.<br>
-    <br>
-
-
-    <blockquote>

-
-    <p>As a finishing touch, we will create an <a href=

-    <h3><a name="iterator_interactions">Iterator Interactions</a></h3>
-
-    <p>C++ allows <tt>const</tt> and non-<tt>const</tt> pointers to interact in
-    the following intuitive ways:
-
-    <ul>
-      <li>a non-<tt>const</tt> pointer to <tt>T</tt> can be implicitly
-      converted to a <tt>const</tt> pointer to <tt>T</tt>.
-
-      <li><tt>const</tt> and non-<tt>const</tt> pointers to <tt>T</tt> can be
-      freely mixed in comparison expressions.
-
-      <li><tt>const</tt> and non-<tt>const</tt> pointers to <tt>T</tt> can be
-      freely subtracted, in any order.
-    </ul>
-
-    Getting user-defined iterators to work together that way is nontrivial (see
-    <a href="reverse_iterator.htm#interactions">here</a> for an example of where
-    the C++ standard got it wrong), but <tt>iterator_adaptor</tt> can make it
-    easy. The rules are as follows:
-
-    <ul>
-      <li><a name="interoperable">Adapted iterators that share the same <tt>Policies</tt>,
-      <tt>Category</tt>, and <tt>Distance</tt> parameters are called
-      <i>interoperable</i>.</a>
-
-      <li>An adapted iterator can be implicitly converted to any other adapted
-      iterator with which it is interoperable, so long as the <tt>Base</tt>
-      type of the source iterator can be converted to the <tt>Base</tt> type of
-      the target iterator.
-
-      <li>Interoperable iterators can be freely mixed in comparison expressions
-      so long as the <tt>Policies</tt> class has <tt>equal</tt> (and, for
-      random access iterators, <tt>less</tt>) members that can accept both
-      <tt>Base</tt> types in either order.
-
-      <li>Interoperable iterators can be freely mixed in subtraction
-      expressions so long as the <tt>Policies</tt> class has a
-      <tt>distance</tt> member that can accept both <tt>Base</tt> types in
-      either order.
-    </ul>
-
-    <h4>Example</h4>
-    
-    <p>The <a href="projection_iterator.htm">Projection Iterator</a> adaptor is similar to the <a
-href="./transform_iterator.htm">transform iterator adaptor</a> in that
-its <tt>operator*()</tt> applies some function to the result of
-dereferencing the base iterator and then returns the result. The
-difference is that the function must return a reference to some
-existing object (for example, a data member within the
-<tt>value_type</tt> of the base iterator). 
-
-    <p>
-The <a
-    href="projection_iterator.htm#projection_iterator_pair_generator">projection_iterator_pair_generator</a> template
-    is a special two-<a href="../../more/generic_programming.html#type_generator">type generator</a> for mutable and constant versions of a
-    projection iterator. It is defined as follows:
-<blockquote>
-<pre>
-template &lt;class AdaptableUnaryFunction, class Iterator, class ConstIterator&gt;
-struct projection_iterator_pair_generator {
-    typedef typename AdaptableUnaryFunction::result_type value_type;
-    typedef projection_iterator_policies&lt;AdaptableUnaryFunction&gt; policies;

-        const value_type&amp;,const value_type*&gt; const_iterator;
-};
-</pre>
-</blockquote>
-
-<p>It is assumed that the <tt>Iterator</tt> and <tt>ConstIterator</tt> arguments are corresponding mutable
-and constant iterators. <ul>
-<li>
-Clearly, then, the
-<tt>projection_iterator_pair_generator</tt>'s <tt>iterator</tt> and
-<tt>const_iterator</tt> are <a href="#interoperable">interoperable</a>, since

-<a href="#template_parameters">default template parameters</a> to
-<tt>iterator_adaptor</tt> should be the same.
-
-<li>Since <tt>Iterator</tt> can presumably be converted to
-<tt>ConstIterator</tt>, the projection <tt>iterator</tt> will be convertible to
-the projection <tt>const_iterator</tt>.
-
-<li> Since <tt>projection_iterator_policies</tt> implements only the

-    <p><a name="1">[1]</a> The standard specifies that the <tt>value_type</tt>
-    of <tt>const</tt> iterators to <tt>T</tt> (e.g. <tt>const T*</tt>) is
-    <tt><i>non-</i>const T</tt>, while the <tt>pointer</tt> and
-    <tt>reference</tt> types for all <a href=
-    "http://www.sgi.com/tech/stl/ForwardIterator.html">Forward Iterators</a> are
-    <tt>const T*</tt> and <tt>const T&amp;</tt>, respectively. Stripping the
-    <tt>const</tt>-ness of <tt>Value</tt> allows you to easily
-    make a <tt>const</tt> iterator adaptor by supplying a <tt>const</tt> type
-    for <tt>Value</tt>, and allowing the defaults for the <tt>Pointer</tt> and
-    <tt>Reference</tt> parameters to take effect. Although compilers that don't
-    support partial specialization won't strip <tt>const</tt> for you, having a
-    <tt>const value_type</tt> is often harmless in practice.
-
-    <p><a name="2">[2]</a> If your compiler does not support partial
-    specialization and the base iterator is a builtin pointer type, you
-    will not be able to use the default for <tt>Value</tt> and will have to
-    specify this type explicitly.
-
-    <p><a name="3">[3]</a> The result type for the <tt>operator-&gt;()</tt>
-    depends on the category and value type of the iterator and is somewhat
-    complicated to describe. But be assured, it works in a stardard conforming
-    fashion, providing access to members of the objects pointed to by the
-    iterator.
-
-    <p><a name="4">[4]</a> The result type of <tt>operator[]()</tt> is
-    <tt>value_type</tt> instead of <tt>reference</tt> as might be expected.
-    There are two reasons for this choice. First, the C++ standard only
-    requires that the return type of an arbitrary <a href=
-    "http://www.sgi.com/tech/stl/RandomAccessIterator.html">Random Access
-    Iterator</a>'s <tt>operator[]</tt>be ``convertible to T'' (Table 76), so
-    when adapting an arbitrary base iterator we may not have a reference to
-    return. Second, and more importantly, for certain kinds of iterators,
-    returning a reference could cause serious memory problems due to the
-    reference being bound to a temporary object whose lifetime ends inside of
-    the <tt>operator[]</tt>.
-
-    <p><a name="5">[5]</a>
-    The <tt>value_type</tt> of an iterator may not be
-    an abstract base class, however many common uses of iterators
-    never need the <tt>value_type</tt>, only the <tt>reference</tt> type.
-    If you wish to create such an iterator adaptor, use a dummy
-    type such as <tt>char</tt> for the <tt>Value</tt> parameter,
-    and use a reference to your abstract base class for
-    the <tt>Reference</tt> parameter. Note that such an iterator
-    does not fulfill the C++ standards requirements for a
-    <a href= "http://www.sgi.com/tech/stl/ForwardIterator.html">
-    Forward Iterator</a>, so you will need to use a less restrictive
-    iterator category such as <tt>std::input_iterator_tag</tt>.

-The projection iterator adaptor is similar to the <a

-its <tt>operator*()</tt> applies some function to the result of
-dereferencing the base iterator and then returns the result. The
-difference is that the function must return a reference to some
-existing object (for example, a data member within the
-<tt>value_type</tt> of the base iterator). The following
-<b>pseudo-code</b> gives the basic idea. The data member <tt>p</tt> is
-the function object.

-    <h2><a name="reverse_iterator_generator">The Reverse Iterator Type
-    Generator</a></h2>
-    The <tt>reverse_iterator_generator</tt> template is a <a href=
-    "../../more/generic_programming.html#type_generator">generator</a> of
-    reverse iterator types. The main template parameter for this class is the
-    base <tt>BidirectionalIterator</tt> type that is being adapted. In most
-    cases the associated types of the base iterator can be deduced using
-    <tt>std::iterator_traits</tt>, but in some situations the user may want to
-    override these types, so there are also template parameters for the base
-    iterator's associated types.

-
-    <h3>Example</h3>
-    In this example we sort a sequence of letters and then output the sequence
-    in descending order using reverse iterators. 
-
-    <blockquote>
-<pre>
-#include &lt;boost/config.hpp&gt;
-#include &lt;iostream&gt;
-#include &lt;algorithm&gt;
-#include &lt;boost/iterator_adaptors.hpp&gt;
-
-int main(int, char*[])
-{
-  char letters[] = "hello world!";
-  const int N = sizeof(letters)/sizeof(char) - 1;
-  std::cout &lt;&lt; "original sequence of letters:\t"
-      &lt;&lt; letters &lt;&lt; std::endl;
-
-  std::sort(letters, letters + N);
-
-  // Use reverse_iterator_generator to print a sequence
-  // of letters in reverse order.
-  
-  boost::reverse_iterator_generator&lt;char*&gt;::type
-    reverse_letters_first(letters + N),
-    reverse_letters_last(letters);
-
-  std::cout &lt;&lt; "letters in descending order:\t";
-  std::copy(reverse_letters_first, reverse_letters_last,
-      std::ostream_iterator&lt;char&gt;(std::cout));
-  std::cout &lt;&lt; std::endl;
-
-  // to be continued...
-</pre>
-    </blockquote>
-    The output is: 
-
-    <blockquote>
-<pre>
-original sequence of letters: hello world!
-letters in descending order:  wroolllhed!

-    <h3>Concept Model</h3>
-    The indirect iterator will model whichever <a href=
-    "http://www.sgi.com/tech/stl/Iterators.html">standard iterator concept
-    category</a> is modeled by the base iterator. Thus, if the base iterator is
-    a model of <a href=
-    "http://www.sgi.com/tech/stl/RandomAccessIterator.html">Random Access
-    Iterator</a> then so is the resulting indirect iterator. If the base
-    iterator models a more restrictive concept, the resulting indirect iterator
-    will model the same concept. The base iterator must be at least a <a href=
-    "http://www.sgi.com/tech/stl/BidirectionalIterator.html">Bidirectional
-    Iterator</a> 
-
-    <h3>Members</h3>
-    The reverse iterator type implements the member functions and operators
-    required of the <a href=
-    "http://www.sgi.com/tech/stl/RandomAccessIterator.html">Random Access
-    Iterator</a> concept. In addition it has the following constructor: 
-
-    <blockquote>
-<pre>
-reverse_iterator_generator::type(const BidirectionalIterator&amp; it)
-</pre>
-    </blockquote>

-    <h2><a name="make_reverse_iterator">The Reverse Iterator Object
-    Generator</a></h2>
-    The <tt>make_reverse_iterator()</tt> function provides a more convenient
-    way to create reverse iterator objects. The function saves the user the
-    trouble of explicitly writing out the iterator types. 
-
-    <blockquote>
-<pre>
-template &lt;class BidirectionalIterator&gt;
-typename reverse_iterator_generator&lt;BidirectionalIterator&gt;::type
-make_reverse_iterator(BidirectionalIterator base);
-</pre>
-    </blockquote>
-
-    <h3>Example</h3>
-    In this part of the example we use <tt>make_reverse_iterator()</tt> to
-    print the sequence of letters in reverse-reverse order, which is the
-    original order. 
-
-    <blockquote>
-<pre>
-  // continuing from the previous example...
-
-  std::cout &lt;&lt; "letters in ascending order:\t";
-  std::copy(boost::make_reverse_iterator(reverse_letters_last),
-      boost::make_reverse_iterator(reverse_letters_first),
-      std::ostream_iterator&lt;char&gt;(std::cout));
-  std::cout &lt;&lt; std::endl;
-
-  return 0;
-}

-    <h2><a name="interactions">Constant/Mutable Iterator Interactions</a></h2>
-
-    <p>One failing of the standard <tt><a
-    href="http://www.sgi.com/tech/stl/ReverseIterator.html">reverse_iterator</a></tt>
-    adaptor is that it doesn't properly support interactions between adapted
-    <tt>const</tt> and non-<tt>const</tt> iterators. For example:
-<blockquote>
-<pre>
-#include &lt;vector&gt;
-
-template &lt;class T&gt; void convert(T x) {}
-
-// Test interactions of a matched pair of random access iterators
-template &lt;class Iterator, class ConstIterator&gt;
-void test_interactions(Iterator i, ConstIterator ci)
-{
-  bool eq = i == ci;               // comparisons
-  bool ne = i != ci;            
-  bool lt = i &lt; ci;
-  bool le = i &lt;= ci;
-  bool gt = i &gt; ci;
-  bool ge = i &gt;= ci;
-  std::size_t distance = i - ci;   // difference
-  ci = i;                          // assignment
-  ConstIterator ci2(i);            // construction
-  convert&lt;ConstIterator&gt;(i);       // implicit conversion
-}
-
-void f()
-{
-  typedef std::vector&lt;int&gt; vec;
-  vec v;
-  const vec&amp; cv;
-
-  test_interactions(v.begin(), cv.begin());   // <font color="#007F00">OK</font>
-  test_interactions(v.rbegin(), cv.rbegin()); // <font color="#FF0000">ERRORS ON EVERY TEST!!</font>
-</pre>
-</blockquote>
-Reverse iterators created with <tt>boost::reverse_iterator_generator</tt> don't have this problem, though:
-<blockquote>
-<pre>
-  typedef boost::reverse_iterator_generator&lt;vec::iterator&gt;::type ri;
-  typedef boost::reverse_iterator_generator&lt;vec::const_iterator&gt;::type cri;
-  test_interactions(ri(v.begin()), cri(cv.begin()));   // <font color="#007F00">OK!!</font>
-</pre>
-</blockquote>
-Or, more simply,
-<blockquote>
-<pre>
-  test_interactions(
-    boost::make_reverse_iterator(v.begin()), 
-    boost::make_reverse_iterator(cv.begin()));   // <font color="#007F00">OK!!</font>
-}
-</pre>
-</blockquote>
-
-<p>If you are wondering why there is no
-<tt>reverse_iterator_pair_generator</tt> in the manner of <tt><a
-href="projection_iterator.htm#projection_iterator_pair_generator">projection_iterator_pair_generator</a></tt>,
-the answer is simple: we tried it, but found that in practice it took
-<i>more</i> typing to use <tt>reverse_iterator_pair_generator</tt> than to
-simply use <tt>reverse_iterator_generator</tt> twice!<br><br>
