-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 as 
-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.

 requirement from the contained type since objects can be directly constructed in-place without need of a copy.<br>

-    <h1>Swap</h1>
-    
-    <p>
-      <tt>template&lt;class T&gt; void swap(T&amp; <em>left</em>, T&amp; <em>right</em>);</tt>
-    </p>
-     
-    <!-- Introduction -->
-    <p>
-      The template function <tt>boost::swap</tt> allows the values of two variables to be swapped, using argument dependent lookup to select a specialized swap function if available. If no specialized swap function is available, <tt>std::swap</tt> is used.
-    </p>
-    
-    <!-- Rationale -->
-    <h2>Rationale</h2>
-    <p>
-      The generic <tt>std::swap</tt> function requires that the elements to be swapped are assignable and copy constructible. It is usually implemented using one copy construction and two assignments - this is often both unnecessarily restrictive and unnecessarily slow. In addition, where the generic swap implementation provides only the basic guarantee, specialized swap functions are often able to provide the no-throw exception guarantee (and it is considered best practice to do so where possible<sup><a href="#ref1">1</a></sup>).</p>
-    <p>
-      The alternative to using argument dependent lookup in this situation is to provide a template specialization of <tt>std::swap</tt> for every type that requires a specialized swap. Although this is legal C++, no Boost libraries use this method, whereas many Boost libraries provide specialized swap functions in their own namespaces.
-    </p>
-    <p>
-      <tt>boost::swap</tt> also supports swapping built-in arrays. Note that <tt>std::swap</tt> originally did not do so, but a request to add an overload of <tt>std::swap</tt> for built-in arrays has been accepted by the C++ Standards Committee<sup><a href="#ref2">2</a></sup>.
-    </p>
-    
-    <!-- Exception Safety -->
-    <h2>Exception Safety</h2>
-    <p>
-      <tt>boost::swap</tt> provides the same exception guarantee as the underlying swap function used, with one exception; for an array of type <tt>T[n]</tt>, where <tt>n > 1</tt> and the underlying swap function for <tt>T</tt> provides the strong exception guarantee, <tt>boost::swap</tt> provides only the basic exception guarantee.
-    </p>
-    
-    <!-- Requirements -->
-    <h2>Requirements</h2>
-    <p>Either:</p>
-    <ul>      
-      <li>T must be assignable</li>
-      <li>T must be copy constructible</li>
-    </ul>
-    <p>Or:</p>
-    <ul>
-      <li>A function with the signature <tt>swap(T&amp;,T&amp;)</tt> is available via argument dependent lookup</li>
-    </ul>
-    <p>Or:</p>
-    <ul>
-      <li>A template specialization of <tt>std::swap</tt> exists for T</li>
-    </ul>
-    <p>Or:</p>
-    <ul>
-      <li>T is a built-in array of swappable elements</li>
-    </ul>
-
-    
-    <!-- Portability -->
-    <h2>Portability</h2>
-    <p>
-      Several older compilers do not support argument dependent lookup &#x2012; on these compilers <tt>boost::swap</tt> will call <tt>std::swap</tt>, ignoring any specialized swap functions that could be found as a result of argument dependent lookup.

-The template class <code>boost::initialized&lt;T&gt;</code> supports both value-initialization
-and direct-initialization, so its interface is a superset of the interface
-of <code>value_initialized&lt;T&gt;</code>: Its default-constructor 
-value-initializes the wrapped object just like the default-constructor of
-<code>value_initialized&lt;T&gt;</code>, but <code>boost::initialized&lt;T&gt;</code>
-also offers an extra <code>explicit</code>
-constructor, which direct-initializes the wrapped object by the specified value.
-<p>
-
-<code>initialized&lt;T&gt;</code> is especially useful when the wrapped
-object must be either value-initialized or direct-initialized, depending on
-runtime conditions. For example, <code>initialized&lt;T&gt;</code> 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 <i>always</i> be value-initialized, <code>value_initialized&lt;T&gt;</code>
-may be preferable. And if the object must always be
-direct-initialized, none of the two wrappers really needs to be used.
