       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>

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 was that some compilers 
-     didn't accept the following valid code:</p>
+<p>But notice that this conversion operator is to <code>T&amp;</code> although 
+    it is itself <code>const</code>. As a consequence, if <code>T</code> is

-<p>The current version of <code>value_initialized</code> no longer has this obscure behavior.
-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.
-<br>
+<p>These compilers complain about ambiguity between the conversion operators. 
+    This complaint is incorrect, but the only workaround that I know of is 
+ to   provide only one of them, which leads to the obscure behavior just explained.<br>
