+MultiPassInputIterator
+</H2>
+
+This concept is a refinement of <a
+href="http://www.sgi.com/Technology/STL/InputIterator.html">InputIterator</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
+MultiPassInputIterator is very similar to the <a
+href="http://www.sgi.com/Technology/STL/ForwardIterator.hmtl">ForwardIterator</a>. The
+only difference is that a <a
+href="http://www.sgi.com/Technology/STL/ForwardIterator.hmtl">ForwardIterator</a>
+requires the <TT>reference</TT> type to be <TT>value_type&amp;</TT>, whereas
+MultiPassInputIterator is like <a
+href="http://www.sgi.com/Technology/STL/InputIterator.html">InputIterator</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 MultiPassInputIterator isn't the right
+solution. Do you also want to define MultiPassBidirectionnalIterator
+and MultiPassRandomAccessIterator ? 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 RandomAccess 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 MultiPassInputIterator
+is just called a ForwardIterator.
+
+<p>                
+Other translations are:<br>
+std::ForwardIterator -> ForwardIterator & LvalueIterator<br>
+std::BidirectionnalIterator -> BidirectionnalIterator & LvalueIterator<br>
+std::RandomAccessIterator -> RandomAccessIterator & LvalueIterator<br>
+
+<p>
+Note that in practice the only operation not allowed on my 
+ForwardIterator which is allowed on std::ForwardIterator 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 ForwardIterator. The right course
+of action is to get ForwardIterator, etc. changed in the C++ standard.
+Once that is done we can drop MultiPassInputIterator.

-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 align="center"><em>by John Maddock and Steve Cleary</em></p>
+<p align="center"><em>This is a draft of an article that will appear in a future
+issue of </em><a href="http://www.ddj.com"><em>Dr Dobb's Journal</em></a></p>
+<p>Generic programming (writing code which works with any data type meeting a
+set of requirements) has become the method of choice for providing reusable
+code. However, there are times in generic programming when &quot;generic&quot;
+just isn't good enough - sometimes the differences between types are too large
+for an efficient generic implementation. This is when the traits technique
+becomes important - by encapsulating those properties that need to be considered
+on a type by type basis inside a traits class, we can minimise the amount of
+code that has to differ from one type to another, and maximise the amount of
+generic code.</p>
+<p>Consider an example: when working with character strings, one common
+operation is to determine the length of a null terminated string. Clearly it's
+possible to write generic code that can do this, but it turns out that there are
+much more efficient methods available: for example, the C library functions <font size="2" face="Courier New">strlen</font>
+and <font size="2" face="Courier New">wcslen</font> are usually written in
+assembler, and with suitable hardware support can be considerably faster than a
+generic version written in C++. The authors of the C++ standard library realised
+this, and abstracted the properties of <font size="2" face="Courier New">char</font>
+and <font size="2" face="Courier New">wchar_t</font> into the class <font size="2" face="Courier New">char_traits</font>.
+Generic code that works with character strings can simply use <font size="2" face="Courier New">char_traits&lt;&gt;::length</font>
+to determine the length of a null terminated string, safe in the knowledge that
+specialisations of <font size="2" face="Courier New">char_traits</font> will use
+the most appropriate method available to them.</p>
+<h4>Type traits</h4>
+<p>Class <font size="2" face="Courier New">char_traits</font> is a classic
+example of a collection of type specific properties wrapped up in a single class
+- what Nathan Myers termed a <i>baggage class</i>[1]. In the Boost type-traits
+library, we[2] have written a set of very specific traits classes, each of which
+encapsulate a single trait from the C++ type system; for example, is a type a
+pointer or a reference type? Or does a type have a trivial constructor, or a
+const-qualifier? The type-traits classes share a unified design: each class has
+a single member <i>value</i>, a compile-time constant that is true if the type
+has the specified property, and false otherwise. As we will show, these classes
+can be used in generic programming to determine the properties of a given type
+and introduce optimisations that are appropriate for that case.</p>
+<p>The type-traits library also contains a set of classes that perform a
+specific transformation on a type; for example, they can remove a top-level
+const or volatile qualifier from a type. Each class that performs a
+transformation defines a single typedef-member <i>type</i> that is the result of
+the transformation. All of the type-traits classes are defined inside namespace <font size="2" face="Courier New">boost</font>;
+for brevity, namespace-qualification is omitted in most of the code samples
+given.</p>
+<h4>Implementation</h4>
+<p>There are far too many separate classes contained in the type-traits library
+to give a full implementation here - see the source code in the Boost library
+for the full details - however, most of the implementation is fairly repetitive
+anyway, so here we will just give you a flavour for how some of the classes are
+implemented. Beginning with possibly the simplest class in the library, is_void&lt;T&gt;
+has a member <i>value</i> that is true only if T is void.</p>
+<pre>template &lt;typename T&gt; 
+struct is_void
+{ static const bool value = false; };
+
+template &lt;&gt; 
+struct is_void&lt;void&gt;
+{ static const bool value = true; };</pre>
+<p>Here we define a primary version of the template class <font size="2" face="Courier New">is_void</font>,
+and provide a full-specialisation when T is void. While full specialisation of a
+template class is an important technique, sometimes we need a solution that is
+halfway between a fully generic solution, and a full specialisation. This is
+exactly the situation for which the standards committee defined partial
+template-class specialisation. As an example, consider the class
+boost::is_pointer&lt;T&gt;: here we needed a primary version that handles all
+the cases where T is not a pointer, and a partial specialisation to handle all
+the cases where T is a pointer:</p>
+<pre>template &lt;typename T&gt; 
+struct is_pointer 
+{ static const bool value = false; };
+
+template &lt;typename T&gt; 
+struct is_pointer&lt;T*&gt; 
+{ static const bool value = true; };</pre>
+<p>The syntax for partial specialisation is somewhat arcane and could easily
+occupy an article in its own right; like full specialisation, in order to write
+a partial specialisation for a class, you must first declare the primary
+template. The partial specialisation contains an extra &lt;<EFBFBD>&gt; after the
+class name that contains the partial specialisation parameters; these define the
+types that will bind to that partial specialisation rather than the default
+template. The rules for what can appear in a partial specialisation are somewhat
+convoluted, but as a rule of thumb if you can legally write two function
+overloads of the form:</p>
+<pre>void foo(T);
+void foo(U);</pre>
+<p>Then you can also write a partial specialisation of the form:</p>
+<pre>template &lt;typename T&gt;
+class c{ /*details*/ };
+
+template &lt;typename T&gt;
+
+class c&lt;U&gt;{ /*details*/ };</pre>
+<p>This rule is by no means foolproof, but it is reasonably simple to remember
+and close enough to the actual rule to be useful for everyday use.</p>
+<p>As a more complex example of partial specialisation consider the class
+remove_bounds&lt;T&gt;. This class defines a single typedef-member <i>type</i>
+that is the same type as T but with any top-level array bounds removed; this is
+an example of a traits class that performs a transformation on a type:</p>
+<pre>template &lt;typename T&gt; 
+struct remove_bounds
+{ typedef T type; };
+
+template &lt;typename T, std::size_t N&gt; 
+struct remove_bounds&lt;T[N]&gt;
+{ typedef T type; };</pre>
+<p>The aim of remove_bounds is this: imagine a generic algorithm that is passed
+an array type as a template parameter, <font size="2" face="Courier New">remove_bounds</font>
+provides a means of determining the underlying type of the array. For example <code>remove_bounds&lt;int[4][5]&gt;::type</code>
+would evaluate to the type <code>int[5]</code>. This example also shows that the
+number of template parameters in a partial specialisation does not have to match
+the number in the default template. However, the number of parameters that
+appear after the class name do have to match the number and type of the
+parameters in the default template.</p>
+<h4>Optimised copy</h4>
+<p>As an example of how the type traits classes can be used, consider the
+standard library algorithm copy:</p>
+<pre>template&lt;typename Iter1, typename Iter2&gt;
+Iter2 copy(Iter1 first, Iter1 last, Iter2 out);</pre>
+<p>Obviously, there's no problem writing a generic version of copy that works
+for all iterator types Iter1 and Iter2; however, there are some circumstances
+when the copy operation can best be performed by a call to <font size="2" face="Courier New">memcpy</font>.
+In order to implement copy in terms of <font size="2" face="Courier New">memcpy</font>
+all of the following conditions need to be met:</p>
+<ul>
+  <li>Both of the iterator types Iter1 and Iter2 must be pointers.</li>
+  <li>Both Iter1 and Iter2 must point to the same type - excluding <font size="2" face="Courier New">const</font>
+    and <font size="2" face="Courier New">volatile</font>-qualifiers.</li>
+  <li>The type pointed to by Iter1 must have a trivial assignment operator.</li>
+</ul>
+<p>By trivial assignment operator we mean that the type is either a scalar
+type[3] or:</p>
+<ul>
+  <li>The type has no user defined assignment operator.</li>
+  <li>The type does not have any data members that are references.</li>
+  <li>All base classes, and all data member objects must have trivial assignment
+    operators.</li>
+</ul>
+<p>If all these conditions are met then a type can be copied using <font size="2" face="Courier New">memcpy</font>
+rather than using a compiler generated assignment operator. The type-traits
+library provides a class <i>has_trivial_assign</i>, such that <code>has_trivial_assign&lt;T&gt;::value</code>
+is true only if T has a trivial assignment operator. This class &quot;just
+works&quot; for scalar types, but has to be explicitly specialised for
+class/struct types that also happen to have a trivial assignment operator. In
+other words if <i>has_trivial_assign</i> gives the wrong answer, it will give
+the &quot;safe&quot; wrong answer - that trivial assignment is not allowable.</p>
+<p>The code for an optimised version of copy that uses <font size="2" face="Courier New">memcpy</font>
+where appropriate is given in listing 1. The code begins by defining a template
+class <i>copier</i>, that takes a single Boolean template parameter, and has a
+static template member function <font size="2" face="Courier New">do_copy</font>
+which performs the generic version of <font size="2">copy</font> (in other words
+the &quot;slow but safe version&quot;). Following that there is a specialisation
+for <i>copier&lt;true&gt;</i>: again this defines a static template member
+function <font size="2" face="Courier New">do_copy</font>, but this version uses
+memcpy to perform an &quot;optimised&quot; copy.</p>
+<p>In order to complete the implementation, what we need now is a version of
+copy, that calls <code>copier&lt;true&gt;::do_copy</code> if it is safe to use <font size="2" face="Courier New">memcpy</font>,
+and otherwise calls <code>copier&lt;false&gt;::do_copy</code> to do a
+&quot;generic&quot; copy. This is what the version in listing 1 does. To
+understand how the code works look at the code for <font size="2" face="Courier New">copy</font>
+and consider first the two typedefs <i>v1_t</i> and <i>v2_t</i>. These use <code>std::iterator_traits&lt;Iter1&gt;::value_type</code>
+to determine what type the two iterators point to, and then feed the result into
+another type-traits class <i>remove_cv</i> that removes the top-level
+const-volatile-qualifiers: this will allow copy to compare the two types without
+regard to const- or volatile-qualifiers. Next, <font size="2" face="Courier New">copy</font>
+declares an enumerated value <i>can_opt</i> that will become the template
+parameter to copier - declaring this here as a constant is really just a
+convenience - the value could be passed directly to class <font size="2" face="Courier New">copier</font>.
+The value of <i>can_opt</i> is computed by verifying that all of the following
+are true:</p>
+<ul>
+  <li>first that the two iterators point to the same type by using a type-traits
+    class <i>is_same</i>.</li>
+  <li>Then that both iterators are real pointers - using the class <i>is_pointer</i>
+    described above.</li>
+  <li>Finally that the pointed-to types have a trivial assignment operator using
+    <i>has_trivial_assign</i>.</li>
+</ul>
+<p>Finally we can use the value of <i>can_opt</i> as the template argument to
+copier - this version of copy will now adapt to whatever parameters are passed
+to it, if its possible to use <font size="2" face="Courier New">memcpy</font>,
+then it will do so, otherwise it will use a generic copy.</p>
+<h4>Was it worth it?</h4>
+<p>It has often been repeated in these columns that &quot;premature optimisation
+is the root of all evil&quot; [4]. So the question must be asked: was our
+optimisation premature? To put this in perspective the timings for our version
+of copy compared a conventional generic copy[5] are shown in table 1.</p>
+<p>Clearly the optimisation makes a difference in this case; but, to be fair,
+the timings are loaded to exclude cache miss effects - without this accurate
+comparison between algorithms becomes difficult. However, perhaps we can add a
+couple of caveats to the premature optimisation rule:</p>
+<ul>
+  <li>If you use the right algorithm for the job in the first place then
+    optimisation will not be required; in some cases, <font size="2" face="Courier New">memcpy</font>
+    is the right algorithm.</li>
+  <li>If a component is going to be reused in many places by many people then
+    optimisations may well be worthwhile where they would not be so for a single
+    case - in other words, the likelihood that the optimisation will be
+    absolutely necessary somewhere, sometime is that much higher. Just as
+    importantly the perceived value of the stock implementation will be higher:
+    there is no point standardising an algorithm if users reject it on the
+    grounds that there are better, more heavily optimised versions available.</li>
+</ul>

+<h4>Pair of References</h4>
+<p>The optimised copy example shows how type traits may be used to perform
+optimisation decisions at compile-time. Another important usage of type traits
+is to allow code to compile that otherwise would not do so unless excessive
+partial specialization is used. This is possible by delegating partial
+specialization to the type traits classes. Our example for this form of usage is
+a pair that can hold references [6].</p>
+<p>First, let us examine the definition of &quot;std::pair&quot;, omitting the
+comparision operators, default constructor, and template copy constructor for
+simplicity:</p>
+<pre>template &lt;typename T1, typename T2&gt; 
+struct pair 
+{
+  typedef T1 first_type;
+  typedef T2 second_type;
+
+  T1 first;
+  T2 second;
+
+  pair(const T1 &amp; nfirst, const T2 &amp; nsecond)
+  :first(nfirst), second(nsecond) { }
+};</pre>
+<p>Now, this &quot;pair&quot; cannot hold references as it currently stands,
+because the constructor would require taking a reference to a reference, which
+is currently illegal [7]. Let us consider what the constructor's parameters
+would have to be in order to allow &quot;pair&quot; to hold non-reference types,
+references, and constant references:</p>
+<table border="1" cellpadding="7" cellspacing="1" width="638">
+  <tr>
+    <td valign="top" width="50%">Type of &quot;T1&quot;</td>
+    <td valign="top" width="50%">Type of parameter to initializing constructor</td>
+  </tr>
+  <tr>
+    <td valign="top" width="50%">
+      <pre>T</pre>
+    </td>
+    <td valign="top" width="50%">
+      <pre>const T &amp;</pre>
+    </td>
+  </tr>
+  <tr>
+    <td valign="top" width="50%">
+      <pre>T &amp;</pre>

+      <pre>T &amp;</pre>

+    </td>
+    <td valign="top" width="50%">
+      <pre>const T &amp;</pre>
+    </td>
+  </tr>
+</table>
+<p>A little familiarity with the type traits classes allows us to construct a
+single mapping that allows us to determine the type of parameter from the type
+of the contained class. The type traits classes provide a transformation &quot;add_reference&quot;,
+which adds a reference to its type, unless it is already a reference.</p>

+    <td valign="top" width="53%">
+      <pre>const T &amp;</pre>
+    </td>
+  </tr>
+</table>
+<p>This allows us to build a primary template definition for &quot;pair&quot;
+that can contain non-reference types, reference types, and constant reference
+types:</p>
+<pre>template &lt;typename T1, typename T2&gt; 
+struct pair 
+{
+  typedef T1 first_type;
+  typedef T2 second_type;
+
+  T1 first;
+  T2 second;
+
+  pair(boost::add_reference&lt;const T1&gt;::type nfirst,
+       boost::add_reference&lt;const T2&gt;::type nsecond)
+  :first(nfirst), second(nsecond) { }
+};</pre>
+<p>Add back in the standard comparision operators, default constructor, and
+template copy constructor (which are all the same), and you have a std::pair
+that can hold reference types!</p>
+<p>This same extension <i>could</i> have been done using partial template
+specialization of &quot;pair&quot;, but to specialize &quot;pair&quot; in this
+way would require three partial specializations, plus the primary template. Type
+traits allows us to define a single primary template that adjusts itself
+auto-magically to any of these partial specializations, instead of a brute-force
+partial specialization approach. Using type traits in this fashion allows
+programmers to delegate partial specialization to the type traits classes,
+resulting in code that is easier to maintain and easier to understand.</p>
+<h4>Conclusion</h4>
+<p>We hope that in this article we have been able to give you some idea of what
+type-traits are all about. A more complete listing of the available classes are
+in the boost documentation, along with further examples using type traits.
+Templates have enabled C++ uses to take the advantage of the code reuse that
+generic programming brings; hopefully this article has shown that generic
+programming does not have to sink to the lowest common denominator, and that
+templates can be optimal as well as generic.</p>

+  <li>This is actually an issue with the C++ Core Language Working Group (issue

+    a &quot;reference to a reference to T&quot; to mean the same thing as a
+    &quot;reference to T&quot;, but only in template instantiation, in a method
+    similar to multiple cv-qualifiers.</li>
+  <li>For those of you who are wondering why this shouldn't be const-qualified,
+    remember that references are always implicitly constant (for example, you

+    is something completely different. For this reason, cv-qualifiers on

+<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

+<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;Operation::second_argument_type, Operation::result_type&gt; 
+{ 
+protected: 
+   Operation op; 
+   Operation::first_argument_type value; 
+public: 
+   binder1st(const Operation&amp; x, const Operation::first_argument_type&amp; y); 
+   Operation::result_type operator()(const 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>Operation::result_type operator()(call_traits&lt;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.</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>
+
+<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(call_traits&lt;T&gt;::value_type t);
+};
+
+template &lt;class T&gt;
+void A&lt;T&gt;::foo(call_traits&lt;T&gt;::value_type t)
+{
+   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>

+<h3>Namespace synopsis</h3>
+<blockquote>
+  <pre>namespace boost {
+    namespace cast {
+        // all synopsis below included here
+    }
+  using ::boost::cast::polymorphic_cast;
+  using ::boost::cast::polymorphic_downcast;

+  using ::boost::cast::numeric_cast;
+}</pre>
+</blockquote>
+<h3><a name="Polymorphic_cast">Polymorphic casts</a></h3>
+<p>Pointers to polymorphic objects (objects of classes which define at least one
+virtual function) are sometimes downcast or crosscast.&nbsp; Downcasting means
+casting from a base class to a derived class.&nbsp; Crosscasting means casting
+across an inheritance hierarchy diagram, such as from one base to the other in a
+<b>Y</b> diagram hierarchy.</p>
+<p>Such casts can be done with old-style casts, but this approach is never to be
+recommended.&nbsp; Old-style casts are sorely lacking in type safety, suffer
+poor readability, and are difficult to locate with search tools.</p>
+<p>The C++ built-in <b>static_cast</b> can be used for efficiently downcasting
+pointers to polymorphic objects, but provides no error detection for the case
+where the pointer being cast actually points to the wrong derived class. The <b>polymorphic_downcast</b>
+template retains the efficiency of <b>static_cast</b> for non-debug
+compilations, but for debug compilations adds safety via an assert() that a <b>dynamic_cast</b>
+succeeds.&nbsp;<b>&nbsp;</b></p>
+<p>The C++ built-in <b>dynamic_cast</b> can be used for downcasts and crosscasts
+of pointers to polymorphic objects, but error notification in the form of a
+returned value of 0 is inconvenient to test, or worse yet, easy to forget to
+test.&nbsp; The <b>polymorphic_cast</b> template performs a <b>dynamic_cast</b>,
+and throws an exception if the <b>dynamic_cast</b> returns 0.</p>
+<p>A <b>polymorphic_downcast</b> is preferred when debug-mode tests will cover
+100% of the object types possibly cast and when non-debug-mode efficiency is an
+issue. If these two conditions are not present, <b>polymorphic_cast</b> is
+preferred.&nbsp; It must also be used for crosscasts.&nbsp; It does an assert(
+dynamic_cast&lt;Derived&gt;(x) == x ) where x is the base pointer, ensuring that
+not only is a non-zero pointer returned, but also that it correct in the
+presence of multiple inheritance. .<b> Warning:</b>: Because <b>polymorphic_downcast</b>
+uses assert(), it violates the One Definition Rule if NDEBUG is inconsistently
+defined across translation units.</p>
+<p>The C++ built-in <b>dynamic_cast</b> must be used to cast references rather
+than pointers.&nbsp; It is also the only cast that can be used to check whether
+a given interface is supported; in that case a return of 0 isn't an error
+condition.</p>
+<h3>polymorphic_cast and polymorphic_downcast synopsis</h3>
+<blockquote>
+  <pre>template &lt;class Derived, class Base&gt;
+inline Derived polymorphic_cast(Base* x);
+// Throws: std::bad_cast if ( dynamic_cast&lt;Derived&gt;(x) == 0 )
+// Returns: dynamic_cast&lt;Derived&gt;(x)
+
+template &lt;class Derived, class Base&gt;
+inline Derived polymorphic_downcast(Base* x);
+// Effects: assert( dynamic_cast&lt;Derived&gt;(x) == x );
+// Returns: static_cast&lt;Derived&gt;(x)</pre>
+</blockquote>
+<h3>polymorphic_downcast example</h3>
+<blockquote>
+  <pre>#include &lt;boost/cast.hpp&gt;
+...
+class Fruit { public: virtual ~Fruit(){}; ... };
+class Banana : public Fruit { ... };
+...
+void f( Fruit * fruit ) {
+// ... logic which leads us to believe it is a Banana
+  Banana * banana = boost::polymorphic_downcast&lt;Banana*&gt;(fruit);
+  ...</pre>
+</blockquote>
+<h3><a name="numeric_cast">numeric_cast</a></h3>
+<p>A <b>static_cast</b>, <b>implicit_cast</b> or implicit conversion will not
+detect failure to preserve range for numeric casts. The <b>numeric_cast</b>
+template function are similar to <b>static_cast</b> and certain (dubious)
+implicit conversions in this respect, except that they detect loss of numeric
+range. An exception is thrown when a runtime value preservation check fails.</p>
+<p>The requirements on the argument and result types are:</p>
+<blockquote>
+  <ul>
+    <li>Both argument and result types are CopyConstructible [20.1.3].</li>
+    <li>Both argument and result types are Numeric, defined by <code>std::numeric_limits&lt;&gt;::is_specialized</code>
+      being true.</li>
+    <li>The argument can be converted to the result type using <b>static_cast</b>.</li>
+  </ul>
+</blockquote>
+<h3>numeric_cast synopsis</h3>
+<blockquote>
+  <pre>class bad_numeric_cast : public std::bad_cast {...};
+
+template&lt;typename Target, typename Source&gt;
+  inline Target numeric_cast(Source arg);
+    // Throws:  bad_numeric_cast unless, in converting arg from Source to Target,
+    //          there is no loss of negative range, and no underflow, and no
+    //          overflow, as determined by std::numeric_limits
+    // Returns: static_cast&lt;Target&gt;(arg)</pre>
+</blockquote>
+<h3>numeric_cast example</h3>
+<blockquote>
+  <pre>#include &lt;boost/cast.hpp&gt;
+using namespace boost::cast;
+
+void ariane(double vx)
+{
+    ...
+    unsigned short dx = numeric_cast&lt;unsigned short&gt;(vx);
+    ...
+}</pre>
+</blockquote>
+<h3>numeric_cast rationale</h3>
+<p>The form of the throws condition is specified so that != is not a required
+operation.</p>

+&lt;<a href="../../boost/detail/call_traits.hpp">boost/compressed_pair.hpp</a>&gt;</h2>
+
+<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);
+
+	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 an enumerator type, unless there is
+compiler support for boost::is_enum, or if boost::is_enum is
+specialised for the enumerator type.</p>
+
+<p>Finally, compressed_pair requires compiler support for partial
+specialisation of class templates - without that support
+compressed_pair behaves just like std::pair.</p>

-[#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.

-    {
-    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.
-
-[endsect]
-
-[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 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.

-  ~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
-}
-

-[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 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],

-[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 &
-```
-

-
-[#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

-[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.
-

-[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.
-[endsect]
-
-[/=================]
-[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_of (charT c) const ;
-
-size_type find_first_of(basic_string_view s) const ;
-size_type find_last_of(basic_string_view s) const ;
-size_type find_first_not_of(basic_string_view s) const ;
-size_type find_first_not_of(charT c) const ;
-size_type find_last_not_of(basic_string_view s) 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
-bool starts_with(charT c) const ;
-bool starts_with(basic_string_view x) const ;
-bool ends_with(charT c) const ;
-bool ends_with(basic_string_view x) const ;

-[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.

-[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.

-* Intel support issue 589832, Attempt to value-initialize pointer-to-member triggers internal error on Intel 11.1. Reported by John Maddock, 2010.
-
-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
-[@boost:/libs/config/doc/html/boost_config/boost_macro_reference.html#boost_config.boost_macro_reference.macros_that_describe_defects
-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:
-
-```
-value_initialized<int> x;
-get(x) = 1; // OK
-value_initialized<int const> cx;
-get(x) = 1; // ERROR: Cannot modify a const object
-
-value_initialized<int> const x_c;
-get(x_c) = 1; // ERROR: Cannot modify a const object

-value_initialized<int const> const cx_c;
-get(cx_c) = 1; // ERROR: Cannot modify a const object

-
-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.

-```
-
-__initialized_value__ provides a convenient way to get
-an initialized value: its conversion operator provides an appropriate
-['value-initialized] object for any __CopyConstructible__ type.
-
-Suppose you need to have an initialized variable of type `T`.
-You could do it as follows:
-
-```
-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

-      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>.

-      similar to the following:
-    </p><pre class="programlisting">error: macro "VAR" passed 3 arguments, but takes just 2

-      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

-      Note that, differently from the compiler, the preprocessor only recognizes

-      <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

-
-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).

-//  Revision History
-//  22 Feb 16 Preserve old work-arounds. (Daniel Frey)
-//  16 Dec 10 Limit warning suppression for 4284 to older versions of VC++
-//            (Matthew Bradbury, fixes #4432)
-//  07 Aug 08 Added "euclidean" spelling. (Daniel Frey)
-//  03 Apr 08 Make sure "convertible to bool" is sufficient
-//            for T::operator<, etc. (Daniel Frey)
-//  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

-//            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.

-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.

+<h3><a name="iterator_adaptors">The Iterator Adaptors Class</a></h3>
+
+Implementing standard conforming iterators is a non-trivial task.
+There are some fine-points such as iterator/const_iterator
+interactions and there are the myriad of operators that should be
+implemented but are easily forgotten such as
+<tt>operator-&gt;()</tt>. The purpose of the
+<tt>iterator_adaptors</tt> class is to make it easier to implement an
+iterator class, and even easier to extend and adapt existing iterator
+types. The <tt>iterator_adaptors</tt> class itself is not an adaptor
+class but a <i>type generator</i>. It generates a pair of adaptor classes,
+one class for the mutable iterator and one class for the const
+iterator. The definition of the <tt>iterator_adaptors</tt> class is as
+follows:
+
+<p>
+<TABLE BORDER=0 CELLSPACING=0 CELLPADDING=0 COLS=2>
+<TR><TD WIDTH=30 VALIGN=TOP></TD><TD>
+<PRE>
+template &lt;class Iterator, 
+          class ConstIterator, 
+          class Traits = std::iterator_traits&lt;Iterator&gt;,
+          class ConstTraits = std::iterator_traits&lt;ConstIterator&gt;, 
+          class Policies = default_iterator_policies&gt;
+struct iterator_adaptors
+{
+  typedef ... iterator;
+  typedef ... const_iterator;
+};
+</PRE></TD></TABLE>
+
+<p>The <tt>Iterator</tt> and <tt>ConstIterator</tt> template parameters
+are the iterator types that you want to adapt. The <tt>Traits</tt> and
+<tt>ConstTraits</tt> must be iterator traits classes.  The traits
+parameters default to the specialization of the
+<tt>std::iterator_traits</tt> class for the adapted iterators. If you
+want the traits for your new iterator adaptor (<tt>value_type</tt>,
+<tt>iterator_category</tt>, etc.) to be the same as the adapted
+iterator then use the default, otherwise create your own traits
+classes and pass them in <a href="#1">[1]</a>. 
+
+
+<p>The <tt>Policies</tt> class that you pass in will become the heart of
+the iterator adaptor. The policy class determines how your new adaptor
+class will behave. The <tt>Policies</tt> class must implement 3, 4, or
+7 of the core iterator operations depending on whether you wish the
+new iterator adaptor class to be a
+<a href="http://www.sgi.com/Technology/STL/ForwardIterator.html">
+ForwardIterator</a>,
+<a href="http://www.sgi.com/Technology/STL/BidirectionalIterator.html">
+BidirectionalIterator</a>, or <a
+href="http://www.sgi.com/Technology/STL/RandomAccessIterator.html">
+RandomAccessIterator</a>. Make sure that the
+<tt>iterator_category</tt> type of the traits class you pass in
+matches the category of iterator that you want to create. The default
+policy class, <tt>default_iterator_policies</tt>, implements all 7 of
+the core operations in the usual way. If you wish to create an
+iterator adaptor that only changes a few of the iterator's behaviors,
+then you can have your new policy class inherit from
+<tt>default_iterator_policies</tt> to avoid retyping the usual
+behaviours. You should also look at <tt>default_iterator_policies</tt>
+as the &quot;boiler-plate&quot; for your own policy classes. The
+following is definition of the <tt>default_iterator_policies</tt>
+class:
+

+<h3><a name="iterator_adaptor">The Iterator Adaptor Class</a></h3>
+
+This is the class used inside of the <tt>iterator_adaptors</tt> type
+generator. Use this class directly (instead of using
+<tt>iterator_adaptors</tt>) when there is no difference between the
+const and non-const versions of the iterator type. Often this is
+because there is only a const (read-only) version of the iterator, as
+is the case for <tt>std::set</tt>'s iterators. Use the same type for
+the <tt>Iterator</tt> and <tt>NonconstIterator</tt> template
+arguments.

+struct iterator_adaptor;
+</PRE></TD></TABLE>
+
+
+<p>
+Next we will look at some iterator adaptors that are examples of how
+to use the iterator adaptors class, and that are useful iterator
+adaptors in their own right.
+
+<h3><a name="transform_iterator">The Transform Iterator Class</a></h3>
+
+It is often useful to automatically apply some function to the value
+returned by dereferencing (<tt>operator*()</tt>) an iterator. The
+<tt>transform_iterators</tt> class makes it easy to create an iterator
+adaptor that does just that.
+
+First let us consider what the <tt>Policies</tt> class for the transform
+iterator should look like. We are only changing one of the iterator
+behaviours, so we will inherit from
+<tt>default_iterator_policies</tt>. In addition, we will need a
+function object to apply, so we will have a template parameter and a
+data member for the function object. The function will take one
+argument (the dereferenced value) and we will need to know the
+<tt>result_type</tt> of the function, so <a
+href="http://www.sgi.com/Technology/STL/AdaptableUnaryFunction.html">
+AdaptableUnaryFunction</a> is the corrent concept to choose for the
+function object type. Now for the heart of our iterator adaptor, we
+implement the <tt>dereference</tt> method, applying the function
+object to <tt>*i</tt>. The <tt>type&lt;Reference&gt;</tt> class is
+there to tell you what the reference type of the iterator is, which is
+handy when writing generic iterator adaptors such as this one <a
+href="#2">[2]</a>.
+
+
+<p>
+<TABLE BORDER=0 CELLSPACING=0 CELLPADDING=0 COLS=2>
+<TR><TD WIDTH=30 VALIGN=TOP></TD><TD>
+<PRE>
+  template &lt;class AdaptableUnaryFunction&gt;
+  struct transform_iterator_policies : public default_iterator_policies
+  {
+    transform_iterator_policies(const AdaptableUnaryFunction& f) : m_f(f) { }
+
+    template &lt;class Reference, class Iterator&gt;
+    Reference dereference(type&lt;Reference&gt;, const Iterator& i) const
+      { return m_f(*i); }
+
+    AdaptableUnaryFunction m_f;
+  };
+</PRE></TD></TABLE>
+
+Next we need to create the traits class for our new iterator.  In some
+situations you may need to create a separate traits class for the
+const and non-const iterator types, but here a single traits class
+will do. The <tt>value_type</tt> and <tt>reference</tt> type of our
+transform iterator will be the <tt>result_type</tt> of the function
+object.  The <tt>difference_type</tt> and <tt>iterator_category</tt>
+will be the same as the adapted iterator.
+
+<p>
+<TABLE BORDER=0 CELLSPACING=0 CELLPADDING=0 COLS=2>
+<TR><TD WIDTH=30 VALIGN=TOP></TD><TD>
+<PRE>
+  template &lt;class AdaptableUnaryFunction, class IteratorTraits&gt;
+  struct transform_iterator_traits {
+    typedef typename AdaptableUnaryFunction::result_type value_type;
+    typedef value_type reference;
+    typedef value_type* pointer;
+    typedef typename IteratorTraits::difference_type difference_type;
+    typedef typename IteratorTraits::iterator_category iterator_category;
+  };
+</PRE></TD></TABLE>
+
+The final step is to use the <tt>iterator_adaptor</tt> class to
+construct our transform iterator. We will use the single iterator
+adaptor version because we will not need to create both a mutable and
+const version of the transform iterator. The transform iterator is
+inherently a read-only iterator.  The nicest way to package up our new
+transform iterator is to create a type generator similar to
+<tt>iterator_adaptor</tt>. The first template parameter will be the
+type of the function object. The second parameter will be the adapted
+iterator type. The third parameter is the trait class for
+the adapted iterator.  Inside the <tt>transform_iterators</tt> class
+we use the <tt>transform_iterator_traits</tt> class defined above to
+create the traits class for the new transform iterator. We then use
+the <tt>iterator_adaptor</tt> class to extract the generated
+iterator adaptor type.
+
+<p>
+<TABLE BORDER=0 CELLSPACING=0 CELLPADDING=0 COLS=2>

+The following is a simple example of how to use the

+
+
+<h3><a name="indirect_iterators">The Indirect Iterators Class</a></h3>
+
+It is not all that uncommon to create data structures that consist of
+pointers to pointers. For such a structure it might be nice to have an
+iterator that applies a double-dereference inside the
+<tt>operator*()</tt>. The implementation of this is similar to the

+<h3><a name="reverse_iterators">The Reverse Iterators Class</a></h3>
+
+<p>
+Yes, there is already a <tt>reverse_iterator</tt> adaptor class
+defined in the C++ Standard, but using the <tt>iterator_adaptors</tt>
+class we can re-implement this classic adaptor in a more succinct and
+elegant fashion. Also, this makes for a good example of using
+<tt>iterator_adaptors</tt> that is in familiar territory.
+
+<p>
+The first step is to create the <tt>Policies</tt> class. As in the
+<tt>std::reverse_iterator</tt> class, we need to flip all the
+operations of the iterator. Increment will become decrement, advancing
+by <tt>n</tt> will become retreating by <tt>n</tt>, etc.

+    // this is equivalent to { Iterator tmp = x; return *--tmp; }
+    
+  template &lt;class Iterator&gt;
+  void increment(Iterator& x) const

+
+Since the traits of the reverse iterator adaptor will be the same as
+the adapted iterator's traits, we do not need to create new traits
+classes as was the case for <tt>transform_iterator</tt>. We can skip to

+iterators using the <tt>iterator_adaptor</tt> class.

+<h3><a name="integer_range">The Integer Range Class</a></h3>
+
+The <tt>iterator_adaptors</tt> class can not only be used for adapting
+iterators, but it can also be used to take a non-iterator type and use
+it to build an iterator. An especially simple example of this is
+turning an integer type into an iterator, a counting iterator. The
+builtin integer types of C++ are almost iterators. They have
+<tt>operator++()</tt>, <tt>operator--()</tt>, etc. The one operator
+they are lacking is the <tt>operator*()</tt>, which we will want to
+simply return the current value of the integer. The following few
+lines of code implement the policy and traits class for the counting
+iterator.

+
+Typically we will want to count the integers in some range, so a nice
+interface would be to have a fake container that represents the range
+of integers. The following is the definition of such a class called
+<tt>integer_range</tt>.

+
+<h3>Challenge</h3>
+
+<p>
+There is an unlimited number of ways the the
+<tt>iterator_adaptors</tt> class can be used to create iterators. One
+interesting exercise would be to re-implement the iterators of
+<tt>std::list</tt> and <tt>std::slist</tt> using
+<tt>iterator_adaptors</tt>, where the adapted <tt>Iterator</tt> types
+would be node pointers.
+
+
+<h3>Notes</h3>
+
+<p>
+<a name="1">[1]</a>
+If your compiler does not support partial specialization and hence
+does not have a working <tt>std::iterator_traits</tt> class, you will
+not be able to use the defaults and will need to supply your own
+<tt>Traits</tt> and <tt>ConstTraits</tt> classes.
+
+<p>
+<a name="2">[2]</a>
+The reference type could also be obtained from
+<tt>std::iterator_traits</tt>, but that is not portable on compilers
+that do not support partial specialization.
+
+<p>
+<a name="3">[3]</a>
+It would have been more elegant to implement <tt>indirect_iterators</tt>
+using <tt>transform_iterators</tt>, but for subtle reasons that would require
+the use of <tt>boost::remove_cv</tt> which is not portable.
+
+<h3>Implementation Notes</h3>
+
+The code is somewhat complicated because there are three iterator
+adaptor class: <tt>forward_iterator_adaptor</tt>,
+<tt>bidirectional_iterator_adaptor</tt>, and
+<tt>random_access_iterator_adaptor</tt>. The alternative would be to
+just have one iterator adaptor equivalent to the
+<tt>random_access_iterator_adaptor</tt>.  The reason for going with
+the three adaptors is that according to 14.5.3p5 in the C++ Standard,
+friend functions defined inside a template class body are instantiated
+when the template class is instantiated. This means that if we only
+used the one iterator adaptor, then if the adapted iterator did not
+meet all of the requirements for a
+<a href="http://www.sgi.com/Technology/STL/RandomAccessIterator.html">
+RandomAccessIterator</a> then a compiler error should occur.  Many
+current compilers in fact do not instantiate the friend functions
+unless used, so we could get away with the one iterator adaptor in
+most cases. However, out of respect for the standard this implementation
+uses the three adaptors.

+<h2>Rationale</h2>
+<p>Overloaded operators for class types typically occur in groups. If you can
+write <code>x + y</code>, you probably also want to be able to write <code>x +=
+y</code>. If you can write <code>x &lt; y,</code> you also want <code>x &gt; y,
+x &gt;= y,</code> and <code>x &lt;= y</code>. Moreover, unless your class has
+really surprising behavior, some of these related operators can be defined in
+terms of others (e.g. <code>x &gt;= y <b>&lt;=&gt;</b> !(x &lt; y)</code>).
+Replicating this boilerplate for multiple classes is both tedious and
+error-prone. The <a href="file:///c:/boost/site/boost/operators.hpp">boost/operators.hpp</a>
+templates help by generating operators for you at namespace scope based on other
+operators you've defined in your class.</p>
+<a name="two_arg">
+<h2>Two-Argument Template Forms</h2>
+</a>
+<p>The arguments to a binary operator commonly have identical types, but it is
+not unusual to want to define operators which combine different types. For <a href="#usage">example</a>,
+one might want to multiply a mathematical vector by a scalar. The two-argument
+template forms of the arithmetic operator templates are supplied for this
+purpose. When applying the two-argument form of a template, the desired return
+type of the operators typically determines which of the two types in question
+should be derived from the operator template. For example, if the result of <code>T&nbsp;+&nbsp;U</code>
+is of type <code>T</code>, then <code>T</code> (not <code>U</code>) should be
+derived from <code>addable&lt;T,U&gt;</code>. The comparison templates <code><a href="#less_than_comparable">less_than_comparable&lt;&gt;</a></code>
+and <code><a href="#equality_comparable">equality_comparable&lt;&gt;</a></code>
+are exceptions to this guideline, since the return type of the operators they
+define is <code>bool</code>.</p>
+<p>On compilers which do not support partial specialization, the two-argument
+forms must be specified by using the names shown below with the trailing <code>'2'</code>.
+The single-argument forms with the trailing <code>'1'</code> are provided for
+symmetry and to enable certain applications of the <a href="#chaining">base
+class chaining</a> technique.</p>
+<h2>Arithmetic operators table</h2>
+<p>The requirements for the types used to instantiate operator templates are
+specified in terms of expressions which must be valid and by the return type of
+the expression. In the following table <code>t</code> and <code>t1</code> are
+values of type <code>T</code>, and <code>u</code> is a value of type <code>U</code>.
+Every template in the library other than <a href="#operators"><code>operators&lt;&gt;</code></a>
+and <a href="#operators"><code>operators2&lt;&gt;</code></a> has an additional
+optional template parameter <code>B</code> which is not shown in the table, but
+is explained <a href="#chaining">below</a></p>

+<b><a name="portability">Portability Note:</a></b> many compilers (e.g. MSVC6.3,
+GCC 2.95.2) will not enforce the requirements in this table unless the
+operations which depend on them are actually used. This is not
+standard-conforming behavior. If you are trying to write portable code it is
+important not to rely on this bug. In particular, it would be convenient to
+derive all your classes which need binary operators from the <a href="#operators"><code>operators&lt;&gt;</code></a>
+and <a href="#operators"><code>operators2&lt;&gt;</code></a> templates,
+regardless of whether they implement all the requirements in the table. Even if
+this works with your compiler today, it may not work tomorrow.
+<h2><a name="chaining">Base Class Chaining</a> and Object Size</h2>
+<p>Every template listed in the table except <a href="#operators"><code>operators&lt;&gt;</code></a>
+and <a href="#operators"><code>operators2&lt;&gt;</code></a> has an additional
+optional template parameter <code>B</code>.&nbsp; If supplied, <code>B</code>
+must be a class type; the resulting class will be publicly derived from B. This
+can be used to avoid the object size bloat commonly associated with multiple
+empty base classes (see the <a href="#old_lib_note">note for users of older
+versions</a> below for more details). To provide support for several groups of
+operators, use the additional parameter to chain operator templates into a
+single-base class hierarchy, as in the following <a href="#usage">example</a>.</p>
+<p><b>Caveat:</b> to chain to a base class which is <i>not</i> a boost operator
+template when using the <a href="#two_arg">single-argument form</a><a> of a
+boost operator template, you must specify the operator template with the
+trailing <code>'1'</code> in its name. Otherwise the library will assume you
+mean to define a binary operation combining the class you intend to use as a
+base class and the class you're deriving.</p>
+<p><b>Borland users</b>: even single-inheritance seems to cause an increase in
+object size in some cases. If you are not defining a template, you may get
+better object-size performance by avoiding derivation altogether, and instead
+explicitly instantiating the operator template as follows:
+<pre>
+    class myclass // lose the inheritance...
+    {
+        //...
+    };
+    // explicitly instantiate the operators I need.

+<h2><a name="old_lib_note">Note for users of older versions</a></h2>
+<p>The <a href="#chaining">changes in the library interface and recommended
+usage</a> were motivated by some practical issues described below. The new
+version of the library is still backward-compatible with the former one (so
+you're not <i>forced</i> change any existing code), but the old usage is
+deprecated. Though it was arguably simpler and more intuitive than using <a href="#chaining">base
+class chaining</a>, it has been discovered that the old practice of deriving
+from multiple operator templates can cause the resulting classes to be much
+larger than they should be. Most modern C++ compilers significantly bloat the
+size of classes derived from multiple empty base classes, even though the base
+classes themselves have no state. For instance, the size of <code>point&lt;int&gt;</code>
+from the <a href="#usage">example</a> above was 12-24 bytes on various compilers
+for the Win32 platform, instead of the expected 8 bytes.
+<p>Strictly speaking, it was not the library's fault - the language rules allow
+the compiler to apply the empty base class optimization in that situation. In
+principle an arbitrary number of empty base classes can be allocated at the same
+offset, provided that none of them have a common ancestor (see section 10.5 [class.derived],
+par. 5 of the standard). But the language definition also doesn't <i>require</i>
+implementations to do the optimization, and few if any of today's compilers
+implement it when multiple inheritance is involved. What's worse, it is very
+unlikely that implementors will adopt it as a future enhancement to existing
+compilers, because it would break binary compatibility between code generated by
+two different versions of the same compiler. As Matt Austern said, &quot;One of
+the few times when you have the freedom to do this sort of thing is when you're
+targeting a new architecture...&quot;. On the other hand, many common compilers
+will use the empty base optimization for single inheritance hierarchies.</p>
+<p>Given the importance of the issue for the users of the library (which aims to
+be useful for writing light-weight classes like <code>MyInt</code> or <code>point&lt;&gt;</code>),
+and the forces described above, we decided to change the library interface so
+that the object size bloat could be eliminated even on compilers that support
+only the simplest form of the empty base class optimization. The current library
+interface is the result of those changes. Though the new usage is a bit more
+complicated than the old one, we think it's worth it to make the library more
+useful in real world. Alexy Gurtovoy contributed the code which supports the new
+usage idiom while allowing the library remain backward-compatible.</p>
