https://svn.boost.org/trac10/ticket/12292 <p> Although the documentation of <strong>Boost.Type<code></code>Erasure</strong> explicitly shows how to default-construct an <code>any</code><code></code> from the binding of another <code>any</code>, this seems not to work when rvalue-references are supported by the compiler. </p> <blockquote> <p> The reason is, that the wrong constructor overload is chosen. </p> </blockquote> <p> <code>binding_of</code><code></code> returns a <code>static_binding</code><code></code> for which no explicit <code>any</code>-constructor is available. If rvalue-references are not supported by the compiler the constructor-overload which takes a <code>binding</code><code></code> is chosen (due to implicit conversion from <code>static_binding</code><code></code> to <code>binding</code>). </p> <p> If rvalue-references are supported the constructor which takes a "universal reference" <code>[1]</code><code></code> is chosen instead which does not expect and therefore cannot handle the <code>static_binding</code>. </p> <p> <code>[1]</code> <a class="ext-link" href="https://isocpp.org/blog/2012/11/universal-references-in-c11-scott-meyers"><span class="icon">​</span>https://isocpp.org/blog/2012/11/universal-references-in-c11-scott-meyers</a> </p> en-us /htdocs/site/boost.png https://svn.boost.org/trac10/ticket/12292 Trac 1.4.3 Deniz Bahadir <D.Bahadir@…> Wed, 22 Jun 2016 11:06:50 GMT
