-
-<h2><a name="rationale">Rationale</a></h2>
-
-<p>When developing a class, sometimes a base class needs to be
-initialized with a member of the current class.  As a na&iuml;ve
-example:</p>
-
-<blockquote><pre>
-#include &lt;streambuf&gt;  <i>// for std::streambuf</i>
-#include &lt;ostream&gt;    <i>// for std::ostream</i>
-
-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( &amp;buf )
-        {}
-    //...
-};
-</pre></blockquote>
-
-<p>This is undefined because C++'s initialization order mandates that
-the base class is initialized before the member it uses.  <a
-href="http://www.moocat.org">R. Samuel Klatchko</a> developed a way
-around this by using the initialization order in his favor.  Base
-classes are intialized 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.</p>
-
-<p>A custom base class can be made for this idiom:</p>
-
-<blockquote><pre>
-#include &lt;streambuf&gt;  <i>// for std::streambuf</i>
-#include &lt;ostream&gt;    <i>// for std::ostream</i>
-
-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( &amp;sbuffer )
-        {}
-    //...
-};
-</pre></blockquote>
-
-<p>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.</p>
-
-<p>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.</p>
-
-<p>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.</p>
-
-<h2><a name="synopsis">Synopsis</a></h2>
-
-<blockquote><pre>
-#ifndef BOOST_BASE_FROM_MEMBER_MAX_ARITY
-#define BOOST_BASE_FROM_MEMBER_MAX_ARITY  10
-#endif
-
-template &lt; typename MemberType, int UniqueID = 0 &gt;
-class boost::base_from_member
-{
-protected:
-    MemberType  member;
-
-    base_from_member();
-
-    template&lt; typename T1 &gt;
-    explicit  base_from_member( T1 x1 );
-
-    template&lt; typename T1, typename T2 &gt;
-    base_from_member( T1 x1, T2 x2 );
-
-    //...
-
-    template&lt; typename T1, typename T2, typename T3, typename T4,
-     typename T5, typename T6, typename T7, typename T8, typename T9,
-     typename T10 &gt;
-    base_from_member( T1 x1, T2 x2, T3 x3, T4 x4, T5 x5, T6 x6, T7 x7,
-     T8 x8, T9 x9, T10 x10 );
-};
-</pre></blockquote>
-
-<p>The class template has a first template parameter
-<var>MemberType</var> representing the type of the based-member.
-It has a last template parameter <var>UniqueID</var>, that is an
-<code>int</code>, 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 <var>member</var> that the derived class can use
-for later base classes (or itself).</p>
-
-<p>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.  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.</p>
-
-<p>The <var>BOOST_BASE_FROM_MEMBER_MAX_ARITY</var> 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.)</p>
-
-<h2><a name="usage">Usage</a></h2>
-
-<p>With the starting example, the <code>fdoutbuf</code> sub-object needs
-to be encapsulated in a base class that is inheirited before
-<code>std::ostream</code>.</p>
-
-<blockquote><pre>
-#include &lt;boost/utility/base_from_member.hpp&gt;
-
-#include &lt;streambuf&gt;  <i>// for std::streambuf</i>
-#include &lt;ostream&gt;    <i>// for std::ostream</i>
-
-class fdoutbuf
-    : public std::streambuf
-{
-public:
-    explicit fdoutbuf( int fd );
-    //...
-};
-
-class fdostream
-    : private boost::base_from_member&lt;fdoutbuf&gt;
-    , public std::ostream
-{
-    // Helper typedef's
-    typedef boost::base_from_member&lt;fdoutbuf&gt;  pbase_type;
-    typedef std::ostream                        base_type;
-
-public:
-    explicit fdostream( int fd )
-        : pbase_type( fd ), base_type( &amp;member )
-        {}
-    //...
-};
-</pre></blockquote>
-
-<p>The base-from-member idiom is an implementation detail, so it
-should not be visible to the clients (or any derived classes) of
-<code>fdostream</code>.  Due to the initialization order, the
-<code>fdoutbuf</code> sub-object will get initialized before the
-<code>std::ostream</code> sub-object does, making the former
-sub-object safe to use in the latter sub-object's construction.  Since the
-<code>fdoutbuf</code> sub-object of the final type is the only sub-object
-with the name &quot;member,&quot; that name can be used
-unqualified within the final class.</p>
-
-<h2><a name="example">Example</a></h2>
-
-<p>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.</p>

-<p>The final class has multiple sub-objects with the name
-&quot;member,&quot; so any use of that name needs qualification by
-a name of the appropriate base type.  (Using <code>typedef</code>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 <code>an_int boost::base_from_member&lt;an_int,
-0&gt; :: *</code>) instead of a pointer to the member (having a type of
-<code>an_int *</code>).  The new problem is fixed by qualifying the
-sub-object with &quot;<code>this-&gt;</code>,&quot; and is needed just
-for pointers, and not for references or values.</p>
-
-<p>There are some argument conversions in the initialization.  The
-constructor argument for <code>pbase0_type</code> is converted from
-<code>double</code> to <code>float</code>.  The first constructor
-argument for <code>pbase2_type</code> is converted from <code>int</code>
-to <code>double</code>.  The second constructor argument for
-<code>pbase3_type</code> is a special case of necessary conversion; all
-forms of the null-pointer literal in C++ 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 <code>switcher</code>'s constructor.</p>

-			and two class templates, <STRONG>checked_deleter</STRONG> and <STRONG>checked_array_deleter</STRONG>.
-		</p>
-		<P>The C++ Standard allows, in 5.3.5/5, pointers to incomplete class types to be 
-			deleted with a <EM>delete-expression</EM>. When the class has a non-trivial 
-			destructor, or a class-specific operator delete, the behavior is undefined. 
-			Some compilers issue a warning when an incomplete type is deleted, but 
-			unfortunately, not all do, and programmers sometimes ignore or disable 
-			warnings.</P>
-		<P>A particularly troublesome case is when a smart pointer's destructor, such as <STRONG>
-				boost::scoped_ptr&lt;T&gt;::~scoped_ptr</STRONG>, is instantiated with an 
-			incomplete type. This can often lead to silent, hard to track failures.</P>
-		<P>The supplied function and class templates can be used to prevent these problems, 
-			as they require a complete type, and cause a compilation error otherwise.</P>

-      <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 if either member is a POD type, then that member is not 
-         zero-initialized by the compressed_pair default constructor: it's up to you to 
-         supply an initial value for these types if you want them to have a default 
-         value.</P>
-      <p>Note that compressed_pair can not be instantiated if either of the template 
-         arguments is a union type, unless there is compiler support for 
-         boost::is_union, or if boost::is_union is specialised for the union type.</p>
-      <p>Finally, a word of caution for Visual C++ 6 users: if either argument is an 
-         empty type, then assigning to that member will produce memory corruption, 
-         unless the empty type has a "do nothing" assignment operator defined. This is 
-         due to a bug in the way VC6 generates implicit assignment operators.</p>

+
+[section Rationale]
+
+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 intialized 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.

+        base_from_member( T1 x1, T2 x2 );

+         typename T5, typename T6, typename T7, typename T8, typename T9,
+         typename T10 >
+        base_from_member( T1 x1, T2 x2, T3 x3, T4 x4, T5 x5, T6 x6, T7 x7,
+         T8 x8, T9 x9, T10 x10 );
+    #endif
+    };
+
+    template < typename MemberType, int UniqueID >
+    class base_from_member<MemberType&, UniqueID>
+    {
+    protected:
+        MemberType& member;
+
+        explicit constexpr base_from_member( MemberType& x )
+            noexcept;
+    };
+
+The class template has a first template parameter `MemberType` representing
+the type of the based-member. It has a last template parameter `UniqueID`,
+that is an `int`, to differentiate between multiple base classes that use
+the same based-member type. The last template parameter has a default value
+of zero if it is omitted. The class template has a protected data member
+called `member` that the derived class can use for later base classes (or
+itself).
+
+If the appropriate features of C++11 are present, there will be a single
+constructor template. It implements ['perfect forwarding] to the best
+constructor call of `member` (if any). The constructor template is marked
+both `constexpr` and `explicit`. The former will be ignored if the
+corresponding inner constructor call (of `member`) does not have the marker.
+The latter binds the other way; always taking effect, even when the inner
+constructor call does not have the marker. The constructor template
+propagates the `noexcept` status of the inner constructor call. (The
+constructor template has a trailing parameter with a default value that
+disables the template when its signature is too close to the signatures of
+the automatically-defined non-template copy- and/or move-constructors of
+`base_from_member`.)
+
+On earlier-standard compilers, there is a default constructor and several
+constructor member templates. These constructor templates can take as many
+arguments (currently up to ten) as possible and pass them to a constructor
+of the data member.
+
+A specialization for member references offers a single constructor taking
+a `MemberType&`, which is the only way to initialize a reference.
+
+Since C++ does not allow any way to explicitly state the template parameters
+of a templated constructor, make sure that the arguments are already close
+as possible to the actual type used in the data member's desired constructor.
+Explicit conversions may be necessary.
+
+The `BOOST_BASE_FROM_MEMBER_MAX_ARITY` macro constant specifies the maximum
+argument length for the constructor templates. The constant may be overridden
+if more (or less) argument configurations are needed. The constant may be
+read for code that is expandable like the class template and needs to
+maintain the same maximum size. (Example code would be a class that uses
+this class template as a base class for a member with a flexible set of
+constructors.) This constant is ignored when C++11 features are present.
+
+[endsect]
+
+[section Usage]
+
+With the starting example, the `fdoutbuf` sub-object needs to be
+encapsulated in a base class that is inheirited 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 Example]
+
+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 Overview]
+
+All of the contents of `<boost/compressed_pair.hpp>` are defined inside
+`namespace boost`.
+
+The class `compressed_pair` is very similar to `std::pair`, but if either of
+the template arguments are empty classes, then the ['empty base-class
+optimisation] is applied to compress the size of the pair.
+
+[endsect]
+
+[section Synopsis]
+
+    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 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.
+
+Note that if either member is a POD type, then that member is not
+zero-initialized by the `compressed_pair` default constructor: it's 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::is_union`, or if `boost::is_union` is specialised for the union
+type.
+
+Finally, a word of caution for Visual C++ 6 users: if either argument is an
+empty type, then assigning to that member will produce memory corruption,
+unless the empty type has a "do nothing" assignment operator defined. This
+is due to a bug in the way VC6 generates implicit assignment operators.

+[section Overview]
+[/===============]
+
+The motivation for `declval` was introduced in [@http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2009/n2958.html#Value N2958: 
+Moving Swap Forward]. Here follows a rewording of this chapter.
+
+With the provision of decltype, late-specified return types, and default template-arguments for function templates a 
+new generation of SFINAE patterns will emerge to at least partially compensate the lack of concepts on the C++0x timescale. 
+Using this technique, it is sometimes necessary to obtain an object of a known type in a non-using context, e.g. given the declaration 
+
+  template<class T>
+  T&& declval(); // not used
+  
+as part of the function template declaration 
+
+  template<class To, class From>
+  decltype(static_cast<To>(declval<From>())) convert(From&&);
+  
+or as part of a class template definition 
+
+  template<class> class result_of;
+
+  template<class Fn, class... ArgTypes>
+  struct result_of<Fn(ArgTypes...)> 
+  {
+    typedef decltype(declval<Fn>()(declval<ArgTypes>()...)) type;
+  };
+  
+The role of the function template declval() is a transformation of a type T into a value without using or evaluating this function. 
+The name is supposed to direct the reader's attention to the fact that the expression `declval<T>()` is an lvalue if and only if 
+T is an lvalue-reference, otherwise an rvalue. To extend the domain of this function we can do a bit better by changing its declaration to 
+
+  template<class T>
+  typename std::add_rvalue_reference<T>::type declval(); // not used

+which ensures that we can also use cv void as template parameter. The careful reader might have noticed that `declval()` 
+already exists under the name create() as part of the definition of the semantics of the type trait is_convertible in the C++0x standard. 
+
+The provision of a new library component that allows the production of values in unevaluated expressions is considered 
+important to realize constrained templates in C++0x where concepts are not available. 
+This extremely light-weight function is expected to be part of the daily tool-box of the C++0x programmer.

+      Boost.StringView is an implementation of <code class="computeroutput"><span class="identifier">string_view</span></code>
+      as specified in <a href="http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2015/n4480.html#string.view" target="_top">N4480:
+      ISO/IEC DTS 19568, Technical Specification - C++ Extensions for Library Fundamentals</a>.
+    </p>
+<p>
+      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.
+      The canonical way to do this is as a <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">string</span></code>,
+      but that has certain drawbacks:
+    </p>
+<p>
+      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.
+    </p>
+<p>
+      2) if a routine receives a constant <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">string</span></code>
+      and wants to pass a portion of that string to another routine, then it must
+      create a new string of that substring.
+    </p>
+<p>
+      3) A routine receives a constant <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">string</span></code>
+      and wants to return a portion of the string, then it must create a new string
+      to return.
+    </p>
+<p>
+      <code class="computeroutput"><span class="identifier">string_view</span></code> is designed to
+      solve these efficiency problems. A <code class="computeroutput"><span class="identifier">string_view</span></code>
+      is a read-only reference to a contiguous sequence of characters, and provides
+      much of the functionality of <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">string</span></code>.
+      A <code class="computeroutput"><span class="identifier">string_view</span></code> is cheap to create,
+      copy and pass by value, because it does not actually own the storage that it
+      points to.
+    </p>
+<p>
+      A <code class="computeroutput"><span class="identifier">string_view</span></code> is implemented
+      as a small struct that contains a pointer to the start of the character data
+      and a count. A <code class="computeroutput"><span class="identifier">string_view</span></code>
+      is cheap to create and cheap to copy.
+    </p>
+<p>
+      <code class="computeroutput"><span class="identifier">string_view</span></code> acts as a container;
+      it includes all the methods that you would expect in a container, including
+      iteration support, <code class="computeroutput"><span class="keyword">operator</span> <span class="special">[]</span></code>,
+      <code class="computeroutput"><span class="identifier">at</span></code> and <code class="computeroutput"><span class="identifier">size</span></code>.
+      It can be used with any of the iterator-based algorithms in the STL - as long
+      as you don't need to change the underlying data (<code class="computeroutput"><span class="identifier">sort</span></code>
+      and <code class="computeroutput"><span class="identifier">remove</span></code>, for example, will
+      not work)
+    </p>
+<p>
+      Besides generic container functionality, <code class="computeroutput"><span class="identifier">string_view</span></code>
+      provides a subset of the interface of <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">string</span></code>.
+      This makes it easy to replace parameters of type <code class="computeroutput"><span class="keyword">const</span>
+      <span class="identifier">std</span><span class="special">::</span><span class="identifier">string</span> <span class="special">&amp;</span></code>
+      with <code class="computeroutput"><span class="identifier">boost</span><span class="special">::</span><span class="identifier">string_view</span></code>. Like <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">string</span></code>,
+      <code class="computeroutput"><span class="identifier">string_view</span></code> has a static member
+      variable named <code class="computeroutput"><span class="identifier">npos</span></code> to denote
+      the result of failed searches, and to mean "the end".
+    </p>
+<p>
+      Because a <code class="computeroutput"><span class="identifier">string_view</span></code> does
+      not own the data that it "points to", it introduces lifetime issues
+      into code that uses it. The programmer must ensure that the data that a <code class="computeroutput"><span class="identifier">string_view</span></code> refers to exists as long as the
+      <code class="computeroutput"><span class="identifier">string_view</span></code> does.
+    </p>
+<p>
+      Note: The header actually contains a class template, <code class="computeroutput"><span class="identifier">basic_string_view</span></code>
+      and four typedefs:
+    </p>
+<pre class="programlisting"><span class="keyword">template</span><span class="special">&lt;</span><span class="keyword">class</span> <span class="identifier">charT</span><span class="special">,</span> <span class="keyword">class</span> <span class="identifier">traits</span> <span class="special">=</span> <span class="identifier">char_traits</span><span class="special">&lt;</span><span class="identifier">charT</span><span class="special">&gt;&gt;</span>

+<p>
+      So you can have views of strings of any of the four built-in character types
+      as well as strings of user-defined character-like type strings. For the sake
+      of simple exposition, we concentrate on <code class="computeroutput"><span class="identifier">string_view</span></code>
+      (i.e. <code class="computeroutput"><span class="keyword">char</span></code> strings) in this documentation.

+<p>
+      Integrating <code class="computeroutput"><span class="identifier">string_view</span></code> into

+</pre>
+<p>
+      Let's figure out what happens in this (contrived) example.
+    </p>
+<p>
+      First, a temporary string is created from the string literal <code class="computeroutput"><span class="string">"ABCDEFG"</span></code>, and it is passed (by reference)
+      to the routine <code class="computeroutput"><span class="identifier">extract_part</span></code>.
+      Then a second string is created in the call <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">string</span><span class="special">::</span><span class="identifier">substr</span></code>
+      and returned to <code class="computeroutput"><span class="identifier">extract_part</span></code>
+      (this copy may be elided by RVO). Then <code class="computeroutput"><span class="identifier">extract_part</span></code>
+      returns that string back to the caller (again this copy may be elided). The
+      first temporary string is deallocated, and <code class="computeroutput"><span class="identifier">front</span></code>
+      is called on the second string, and then it is deallocated as well.
+    </p>
+<p>
+      Two <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">string</span></code>s are created, and two copy operations.
+      That's (potentially) four memory allocations and deallocations, and the associated
+      copying of data.
+    </p>
+<p>
+      Now let's look at the same code with <code class="computeroutput"><span class="identifier">string_view</span></code>:
+    </p>
+<pre class="programlisting"><span class="identifier">boost</span><span class="special">::</span><span class="identifier">string_view</span> <span class="identifier">extract_part</span> <span class="special">(</span> <span class="identifier">boost</span><span class="special">::</span><span class="identifier">string_view</span> <span class="identifier">bar</span> <span class="special">)</span> <span class="special">{</span>
+    <span class="keyword">return</span> <span class="identifier">bar</span><span class="special">.</span><span class="identifier">substr</span> <span class="special">(</span> <span class="number">2</span><span class="special">,</span> <span class="number">3</span> <span class="special">);</span>
+    <span class="special">}</span>
+
+<span class="keyword">if</span> <span class="special">(</span> <span class="identifier">extract_part</span> <span class="special">(</span> <span class="string">"ABCDEFG"</span> <span class="special">).</span><span class="identifier">front</span><span class="special">()</span> <span class="special">==</span> <span class="string">"C"</span> <span class="special">)</span> <span class="special">{</span> <span class="comment">/* do something */</span> <span class="special">}</span>
+</pre>
+<p>
+      No memory allocations. No copying of character data. No changes to the code
+      other than the types. There are two <code class="computeroutput"><span class="identifier">string_view</span></code>s
+      created, and two <code class="computeroutput"><span class="identifier">string_view</span></code>s
+      copied, but those are cheap operations.

+      This Boost implementation only requires a C++03 compliant compiler.
+    </p>
+<p>
+      The actual Library Fundamentals specification assumes a C++14 compliant compiler,
+      so a few features are only present if actually supported by the compiler. Boost
+      macros such as BOOST_CONSTEXPR, BOOST_CXX14_CONSTEXPR, and BOOST_NOEXCEPT supply
+      certain features if supported by the compiler.

+
+Boost.StringRef is an 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]. 
+
+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. The canonical way to do this is as 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) 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.
+
+`string_ref` is designed to solve these efficiency problems. A `string_ref` is a read-only reference to a contiguous sequence of characters, and provides much of the functionality of `std::string`. A `string_ref` is cheap to create, copy and pass by value, because it does not actually own the storage that it points to. 
+
+A `string_ref` is implemented as a small struct that contains a pointer to the start of the character data and a count. A `string_ref` is cheap to create and cheap to copy.
+
+`string_ref` 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 don't need to change the underlying data (`sort` and `remove`, for example, will not work)
+
+Besides generic container functionality, `string_ref` provides a subset of the interface of `std::string`. This makes it easy to replace parameters of type `const std::string &` with `boost::string_ref`. Like `std::string`, `string_ref` has a static member variable named `npos` to denote the result of failed searches, and to mean "the end".
+
+Because a `string_ref` does not own the data that it "points to", it introduces lifetime issues into code that uses it. The programmer must ensure that the data that a `string_ref` refers to exists as long as the `string_ref` does.
+
+[endsect]
+
+
+[/===============]
+[section Examples]
+[/===============]
+
+Integrating `string_ref` 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_ref`.
+
+    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's (potentially) four memory allocations and deallocations, and the associated copying of data.
+
+Now let's look at the same code with `string_ref`:
+
+    boost::string_ref extract_part ( boost::string_ref 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_ref`s created, and two `string_ref`s copied, but those are cheap operations.
+
+[endsect]

+[section:reference Reference ]
+[/=================]
+
+The header file "string_ref.hpp" defines a template `boost::basic_string_ref`, and four specializations - for `char` / `wchar_t` / `char16_t` / `char32_t` .
+
+`#include <boost/utility/string_ref.hpp>`
+
+Construction and copying:
+
+    BOOST_CONSTEXPR basic_string_ref ();    // Constructs an empty string_ref
+    BOOST_CONSTEXPR basic_string_ref(const charT* str); // Constructs from a NULL-terminated string
+    BOOST_CONSTEXPR basic_string_ref(const charT* str, size_type len); // Constructs from a pointer, length pair
+    template<typename Allocator>
+    basic_string_ref(const std::basic_string<charT, traits, Allocator>& str); // Constructs from a std::string
+    basic_string_ref (const basic_string_ref &rhs);
+    basic_string_ref& operator=(const basic_string_ref &rhs);
+
+`string_ref` does not define a move constructor nor a move-assignment operator because copying a `string_ref` is just a cheap as moving one.
+
+Basic container-like functions:
+
+    BOOST_CONSTEXPR size_type size()     const ;
+    BOOST_CONSTEXPR size_type length()   const ;
+    BOOST_CONSTEXPR size_type max_size() const ;
+    BOOST_CONSTEXPR bool empty()         const ;
+    
+    // All iterators are const_iterators
+    BOOST_CONSTEXPR const_iterator  begin() const ;
+    BOOST_CONSTEXPR const_iterator cbegin() const ;
+    BOOST_CONSTEXPR const_iterator    end() const ;
+    BOOST_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):
+
+    BOOST_CONSTEXPR const charT& operator[](size_type pos) const ;
+    const charT& at(size_t pos) const ;
+    BOOST_CONSTEXPR const charT& front() const ;
+    BOOST_CONSTEXPR const charT& back()  const ;
+    BOOST_CONSTEXPR const charT* data()  const ;
+
+Modifying the `string_ref` (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_ref s) const ;
+    size_type find(charT c) const ;
+    size_type rfind(basic_string_ref 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_ref s) const ;
+    size_type find_last_of(basic_string_ref s) const ;
+    size_type find_first_not_of(basic_string_ref s) const ;

+    size_type find_last_not_of(basic_string_ref s) const ;
+    size_type find_last_not_of(charT c) const ;
+
+String-like operations:
+
+    BOOST_CONSTEXPR basic_string_ref substr(size_type pos, size_type n=npos) const ; // Creates a new string_ref
+    bool starts_with(charT c) const ;

+
+Boost.StringView is an implementation of `string_view` as specified in [@
+http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2015/n4480.html#string.view N4480:

+
+Note: The header actually contains a class template, `basic_string_view` and four typedefs:
+
+    template<class charT, class traits = char_traits<charT>>
+        class basic_string_view;
+   
+    typedef basic_string_view<char>     string_view;
+    typedef basic_string_view<char16_t> u16string_view;
+    typedef basic_string_view<char32_t> u32string_view;
+    typedef basic_string_view<wchar_t>  wstring_view;
+
+So you can have views of strings of any of the four built-in character types as well as strings of user-defined character-like type strings. For the sake of simple exposition, we concentrate on `string_view` (i.e. `char` strings) in this documentation.

+[section Compiler Support]
+[/===============]
+
+This Boost implementation only requires a C++03 compliant compiler.
+
+The actual Library Fundamentals specification assumes a C++14 compliant compiler, so a few features are only present if actually supported by the compiler. Boost macros such as BOOST_CONSTEXPR, BOOST_CXX14_CONSTEXPR, and BOOST_NOEXCEPT supply certain features if supported by the compiler.

-Sensible operation of template function overloading in C++ relies
-on the <EM>SFINAE</EM> (substitution-failure-is-not-an-error)
-principle&nbsp;[<A HREF="#vandevoorde2002:templates"><CITE>3</CITE></A>]: if an invalid argument
-or return type is formed during the instantiation of a function
-template, the instantiation is removed from the overload resolution
-set instead of causing a compilation error. The following example, 
-taken from&nbsp;[<A HREF="#jarvi:03:cuj_arbitrary_overloading"><CITE>1</CITE></A>],
-demonstrates why this is important:
-<PRE>int negate(int i) { return -i; }
-
-template &lt;class F&gt;
-typename F::result_type negate(const F&amp; f) { return -f(); }
-
-</PRE>
-Suppose the compiler encounters the call <TT>negate(1)</TT>. The first
-definition is obviously a better match, but the compiler must
-nevertheless consider (and instantiate the prototypes) of both
-definitions to find this out. Instantiating the latter definition with
-<TT>F</TT> as <TT>int</TT> would result in:
-<PRE>int::result_type negate(const int&amp;);
-
-</PRE>
-where the return type is invalid. If this was an error, adding an unrelated function template 
-(that was never called) could break otherwise valid code.
-Due to the SFINAE principle the above example is not, however, erroneous. 
-The latter definition of <TT>negate</TT> is simply removed from the overload resolution set.<BR>
-<BR>
-The <TT>enable_if</TT> templates are tools for controlled creation of the SFINAE
-conditions.<BR>
-<BR>
-<!--TOC section The <TT>enable_if</TT> templates-->
-
-<H2><A NAME="htoc4">2</A>&nbsp;&nbsp;The <TT>enable_if</TT> templates</H2><!--SEC END -->
-
-<A NAME="enable_if"></A>
-The names of the <TT>enable_if</TT> templates have three parts: an optional <TT>lazy_</TT> tag, 
-either <TT>enable_if</TT> or <TT>disable_if</TT>, and an optional <TT>_c</TT> tag.
-All eight combinations of these parts are supported.
-The meaning of the <TT>lazy_</TT> tag is described in Section&nbsp;<A HREF="#sec:enable_if_lazy">3.3</A>.
-The second part of the name indicates whether a true condition argument should 
-enable or disable the current overload.
-The third part of the name indicates whether the condition argument is a <TT>bool</TT> value 
-(<TT>_c</TT> suffix), or a type containing a static <TT>bool</TT> constant named <TT>value</TT> (no suffix).
-The latter version interoperates with Boost.MPL. <BR>
-<BR>
-The definitions of <TT>enable_if_c</TT> and <TT>enable_if</TT> are as follows (we use <TT>enable_if</TT> templates 
-unqualified but they are in the <TT>boost</TT> namespace).
-<PRE>template &lt;bool B, class T = void&gt;
-struct enable_if_c {
-  typedef T type;
-};
-
-template &lt;class T&gt;
-struct enable_if_c&lt;false, T&gt; {};
-
-template &lt;class Cond, class T = void&gt;
-struct enable_if : public enable_if_c&lt;Cond::value, T&gt; {};
-
-</PRE>
-An instantiation of the <TT>enable_if_c</TT> template with the parameter
-<TT>B</TT> as <TT>true</TT> contains a member type <TT>type</TT>, defined
-to be <TT>T</TT>. If <TT>B</TT> is
-<TT>false</TT>, no such member is defined. Thus 
-<TT>enable_if_c&lt;B, T&gt;::type</TT> is either a valid or an invalid type
-expression, depending on the value of <TT>B</TT>.
-When valid, <TT>enable_if_c&lt;B, T&gt;::type</TT> equals <TT>T</TT>.
-The <TT>enable_if_c</TT> template can thus be used for controlling when functions are considered for
-overload resolution and when they are not. 
-For example, the following function is defined for all arithmetic types (according to the
-classification of the <A HREF="../type_traits/index.html">Boost type_traits library</A>):
-<PRE>template &lt;class T&gt;
-typename enable_if_c&lt;boost::is_arithmetic&lt;T&gt;::value, T&gt;::type 
-foo(T t) { return t; }
-
-</PRE>
-The <TT>disable_if_c</TT> template is provided as well, and has the
-same functionality as <TT>enable_if_c</TT> except for the negated condition. The following
-function is enabled for all non-arithmetic types.
-<PRE>template &lt;class T&gt;
-typename disable_if_c&lt;boost::is_arithmetic&lt;T&gt;::value, T&gt;::type 
-bar(T t) { return t; }
-
-</PRE>
-For easier syntax in some cases and interoperation with Boost.MPL we provide versions of
-the <TT>enable_if</TT> templates taking any type with a <TT>bool</TT> member constant named 
-<TT>value</TT> as the condition argument.
-The MPL <TT>bool_</TT>, <TT>and_</TT>, <TT>or_</TT>, and <TT>not_</TT> templates are likely to be 
-useful for creating such types. Also, the traits classes in the Boost.Type_traits library 
-follow this convention. 
-For example, the above example function <TT>foo</TT> can be alternatively written as:
-<PRE>template &lt;class T&gt;
-typename enable_if&lt;boost::is_arithmetic&lt;T&gt;, T&gt;::type 
-foo(T t) { return t; }
-
-</PRE>

-The <TT>enable_if</TT> templates are defined in
-<TT>boost/utility/enable_if.hpp</TT>, which is included by <TT>boost/utility.hpp</TT>.<BR>
-<BR>
-The <TT>enable_if</TT> template can be used either as the return type, or as an 
-extra argument. For example, the <TT>foo</TT> function in the previous section could also be written
-as:
-<PRE>template &lt;class T&gt;
-T foo(T t, typename enable_if&lt;boost::is_arithmetic&lt;T&gt; &gt;::type* dummy = 0); 
-
-</PRE>Hence, an extra parameter of type <TT>void*</TT> is added, but it is given 
-a default value to keep the parameter hidden from client code.
-Note that the second template argument was not given to <TT>enable_if</TT>, as the default 
-<TT>void</TT> gives the desired behavior.<BR>
-<BR>
-Whether to write the enabler as an argument or within the return type is
-largely a matter of taste, but for certain functions, only one
-alternative is possible:
-<UL><LI>
-Operators have a fixed number of arguments, thus <TT>enable_if</TT> must be used in the return type.
-<LI>Constructors and destructors do not have a return type; an extra argument is the only option.
-<LI>There does not seem to be a way to specify an enabler for a conversion operator. Converting constructors,
-however, can have enablers as extra default arguments.

-<H3><A NAME="htoc6">3.1</A>&nbsp;&nbsp;Enabling template class specializations</H3><!--SEC END -->
-
-<A NAME="sec:enable_if_classes"></A>
-Class template specializations can be enabled or disabled with <TT>enable_if</TT>.
-One extra template parameter needs to be added for the enabler expressions.
-This parameter has the default value <TT>void</TT>.
-For example:
-<PRE>template &lt;class T, class Enable = void&gt; 
-class A { ... };
-
-template &lt;class T&gt;
-class A&lt;T, typename enable_if&lt;is_integral&lt;T&gt; &gt;::type&gt; { ... };
-
-template &lt;class T&gt;
-class A&lt;T, typename enable_if&lt;is_float&lt;T&gt; &gt;::type&gt; { ... };
-
-</PRE>Instantiating <TT>A</TT> with any integral type matches the first specialization,
-whereas any floating point type matches the second one. All other types
-match the primary template.
-The condition can be any compile-time boolean expression that depends on the 
-template arguments of the class.
-Note that again, the second argument to <TT>enable_if</TT> is not needed; the default (<TT>void</TT>) 
-is the correct value.<BR>
-<BR>
-<!--TOC subsection Overlapping enabler conditions-->
-
-<H3><A NAME="htoc7">3.2</A>&nbsp;&nbsp;Overlapping enabler conditions</H3><!--SEC END -->
-
-<A NAME="sec:overlapping_conditions"></A>
-Once the compiler has examined the enabling conditions and included the
-function into the overload resolution set, normal C++ overload resolution 
-rules are used to select the best matching function.
-In particular, there is no ordering between enabling conditions.
-Function templates with enabling conditions that are not mutually exclusive can 
-lead to ambiguities. For example:
-<PRE>template &lt;class T&gt;
-typename enable_if&lt;boost::is_integral&lt;T&gt;, void&gt;::type 
-foo(T t) {}
-
-template &lt;class T&gt;
-typename enable_if&lt;boost::is_arithmetic&lt;T&gt;, void&gt;::type 
-foo(T t) {}
-
-</PRE>
-All integral types are also arithmetic. Therefore, say, for the call <TT>foo(1)</TT>,
-both conditions are true and both functions are thus in the overload resolution set.
-They are both equally good matches and thus ambiguous.
-Of course, more than one enabling condition can be simultaneously true as long as 
-other arguments disambiguate the functions.<BR>
-<BR>
-The above discussion applies to using <TT>enable_if</TT> in class template
-partial specializations as well.<BR>
-<BR>
-<!--TOC subsection Lazy <TT>enable_if</TT>-->
-
-<H3><A NAME="htoc8">3.3</A>&nbsp;&nbsp;Lazy <TT>enable_if</TT></H3><!--SEC END -->
-
-<A NAME="sec:enable_if_lazy"></A>
-In some cases it is necessary to avoid instantiating part of a
-function signature unless an enabling condition is true. For example:
-<PRE>template &lt;class T, class U&gt; class mult_traits;
-
-template &lt;class T, class U&gt;
-typename enable_if&lt;is_multipliable&lt;T, U&gt;, typename mult_traits&lt;T, U&gt;::type&gt;::type
-operator*(const T&amp; t, const U&amp; u) { ... }
-
-</PRE>Assume the class template <TT>mult_traits</TT> is a traits class defining 
-the resulting type of a multiplication operator. The <TT>is_multipliable</TT> traits
-class specifies for which types to enable the operator. Whenever
-<TT>is_multipliable&lt;A, B&gt;::value</TT> is <TT>true</TT> for some types <TT>A</TT> and <TT>B</TT>,
-then <TT>mult_traits&lt;A, B&gt;::type</TT> is defined.<BR>
-<BR>
-Now, trying to invoke (some other overload) of <TT>operator*</TT> with, say, operand types <TT>C</TT> and <TT>D</TT> 
-for which <TT>is_multipliable&lt;C, D&gt;::value</TT> is <TT>false</TT> 
-and <TT>mult_traits&lt;C, D&gt;::type</TT> is not defined is an error on some compilers. 
-The SFINAE principle is not applied because
-the invalid type occurs as an argument to another template. The <TT>lazy_enable_if</TT> 
-and <TT>lazy_disable_if</TT> templates (and their <TT>_c</TT> versions) can be used in such
-situations:
-<PRE>template&lt;class T, class U&gt;
-typename lazy_enable_if&lt;is_multipliable&lt;T, U&gt;, mult_traits&lt;T, U&gt; &gt;::type
-operator*(const T&amp; t, const U&amp; u) { ... }
-
-</PRE>The second argument of <TT>lazy_enable_if</TT> must be a class type
-that defines a nested type named <TT>type</TT> whenever the first
-parameter (the condition) is true.<BR>
-<BR>
-<!--TOC paragraph Note-->
-
-<H5>Note</H5><!--SEC END -->
-
-Referring to one member type or static constant in a traits class
-causes all of the members (type and static constant) of that
-specialization to be instantiated. Therefore, if your traits classes
-can sometimes contain invalid types, you should use two distinct
-templates for describing the conditions and the type mappings. In the
-above example, <TT>is_multipliable&lt;T, U&gt;::value</TT> defines when
-<TT>mult_traits&lt;T, U&gt;::type</TT> is valid.<BR>
-<BR>
-<!--TOC subsection Compiler workarounds-->
-
-<H3><A NAME="htoc9">3.4</A>&nbsp;&nbsp;Compiler workarounds</H3><!--SEC END -->
-
-<A NAME="sec:workarounds"></A>
-Some compilers flag functions as ambiguous if the only distinguishing factor is a different 
-condition in an enabler (even though the functions could never be ambiguous). For example,
-some compilers (e.g. GCC 3.2) diagnose the following two functions as ambiguous:
-<PRE>template &lt;class T&gt;
-typename enable_if&lt;boost::is_arithmetic&lt;T&gt;, T&gt;::type 
-foo(T t);
-
-template &lt;class T&gt;
-typename disable_if&lt;boost::is_arithmetic&lt;T&gt;, T&gt;::type 
-foo(T t);
-
-</PRE>Two workarounds can be applied:
-<UL><LI>
-Use an extra dummy parameter which disambiguates the functions. Use a default value for
-it to hide the parameter from the caller. For example:
-<PRE>template &lt;int&gt; struct dummy { dummy(int) {} };
-
-template &lt;class T&gt;
-typename enable_if&lt;boost::is_arithmetic&lt;T&gt;, T&gt;::type 
-foo(T t, dummy&lt;0&gt; = 0);
-
-template &lt;class T&gt;
-typename disable_if&lt;boost::is_arithmetic&lt;T&gt;, T&gt;::type 
-foo(T t, dummy&lt;1&gt; = 0);
-</PRE><BR>
-<BR>
-<LI>Define the functions in different namespaces and bring them into a common
-namespace with <TT>using</TT> declarations:
-<PRE>namespace A {
-  template &lt;class T&gt;
-  typename enable_if&lt;boost::is_arithmetic&lt;T&gt;, T&gt;::type 
-  foo(T t);
-}
-
-namespace B {
-  template &lt;class T&gt;
-  typename disable_if&lt;boost::is_arithmetic&lt;T&gt;, T&gt;::type 
-  foo(T t);
-}
-
-using A::foo;
-using B::foo;
-
-</PRE>
-Note that the second workaround above cannot be used for member
-templates. On the other hand, operators do not accept extra arguments,
-which makes the first workaround unusable. As the net effect,
-neither of the workarounds are of assistance for templated operators that
-need to be defined as member functions (assignment and
-subscript operators).

+      Consider the following macro which declares a variable named <code class="computeroutput"><span class="identifier">var</span></code><code class="literal"><span class="emphasis"><em>n</em></span></code>
+      with the specified <code class="literal"><span class="emphasis"><em>type</em></span></code> (see also
+      <a href="../../test/var_error.cpp" target="_top"><code class="literal">var_error.cpp</code></a>):
+    </p><p>
+</p><pre class="programlisting"><span class="preprocessor">#define</span> <span class="identifier">VAR</span><span class="special">(</span><span class="identifier">type</span><span class="special">,</span> <span class="identifier">n</span><span class="special">)</span> <span class="identifier">type</span> <span class="identifier">var</span> <span class="error">#</span><span class="preprocessor"># n</span>
+
+<span class="identifier">VAR</span><span class="special">(</span><span class="keyword">int</span><span class="special">,</span> <span class="number">1</span><span class="special">);</span>                    <span class="comment">// OK.</span>

+</pre><p>
+    </p><p>
+      The first macro invocation works correctly declaring a variable named <code class="computeroutput"><span class="identifier">var1</span></code> of type <code class="computeroutput"><span class="keyword">int</span></code>.
+      However, the second macro invocation fails generating a preprocessor error
+      similar to the following:
+    </p><pre class="programlisting">error: macro "VAR" passed 3 arguments, but takes just 2
+</pre><p>
+      That is because the <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">map</span></code> type passed as the first macro parameter
+      contains a comma <code class="computeroutput"><span class="special">,</span></code> not wrapped
+      by round parenthesis <code class="computeroutput"><span class="special">()</span></code>. The preprocessor
+      interprets that unwrapped comma as a separation between macro parameters concluding
+      that a total of three (and not two) parameters are passed to the macro in the
+      following order:
+    </p><div class="orderedlist"><ol class="orderedlist" type="1"><li class="listitem">
+          <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">map</span><span class="special">&lt;</span><span class="keyword">int</span></code>
+        </li><li class="listitem">
+          <code class="computeroutput"><span class="keyword">char</span><span class="special">&gt;</span></code>
+        </li><li class="listitem">
+          <code class="computeroutput"><span class="number">2</span></code>
+        </li></ol></div><p>
+      Note that, differently from the compiler, the preprocessor only recognizes
+      round parenthesis <code class="computeroutput"><span class="special">()</span></code>. Angular
+      <code class="computeroutput"><span class="special">&lt;&gt;</span></code> and squared <code class="computeroutput"><span class="special">[]</span></code> parenthesis are not recognized by the preprocessor
+      when parsing macro parameters.
+    </p></div><div class="section boost_utility_identitytype_solution" title="Solution"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="boost_utility_identitytype.solution"></a><a class="link" href="#boost_utility_identitytype.solution" title="Solution">Solution</a></h2></div></div></div><p>
+      In some cases, it might be possible to workaround this issue by avoiding to
+      pass the type expression to the macro all together. For example, in the case
+      above a <code class="computeroutput"><span class="keyword">typedef</span></code> could have been
+      used to specify the type expression with the commas outside the macro (see
+      also <a href="../../test/var.cpp" target="_top"><code class="literal">var.cpp</code></a>):
+    </p><p>
+</p><pre class="programlisting"><span class="keyword">typedef</span> <span class="identifier">std</span><span class="special">::</span><span class="identifier">map</span><span class="special">&lt;</span><span class="keyword">int</span><span class="special">,</span> <span class="keyword">char</span><span class="special">&gt;</span> <span class="identifier">map_type</span><span class="special">;</span>
+<span class="identifier">VAR</span><span class="special">(</span><span class="identifier">map_type</span><span class="special">,</span> <span class="number">3</span><span class="special">);</span> <span class="comment">// OK.</span>
+</pre><p>
+    </p><p>
+      When this is neither possible nor desired (e.g., see the function template

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

+
+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.
