       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>
       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 std::swap 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>The reason for this obscure behavior is that some commonly used compilers
-     just don't accept the following valid code:</p>
                    
 <pre>struct X<br>{<br>  operator int&amp;() ;<br>  operator int const&amp;() const ;   <br>};<br>X x ;<br>(x == 1 ) ; // ERROR HERE!</pre>
                     
-<p>These compilers complain about ambiguity between the conversion operators. 
+<p>The current version of <code>value_initialized</code> no longer has this obscure behavior.
-    This complaint is incorrect, but the only workaround that I know of is 
+As compilers nowadays widely support overloading the conversion operator by having a <code>const</code> and a <code>non-const</code> version, we have decided to fix the issue accordingly. So the current version supports the idea of logical constness.
- to   provide only one of them, which leads to the obscure behavior just explained.<br>
