https://svn.boost.org/trac10/ticket/10041 <p> When trying to compile </p> <pre class="wiki">typedef boost::mpl::set2&lt; std::string, int &gt; types; boost::make_variant_over&lt; types &gt;::type v1; </pre><p> MPL compile-time assertion notifies about missing push_front specialization. At least documentation should be refined. Now is says <em>Sequence is any type fulfilling the requirements of MPL's Sequence concept</em>. But probably code may be changed for more general solution. </p> en-us /htdocs/site/boost.png https://svn.boost.org/trac10/ticket/10041 Trac 1.4.3 Antony Polukhin Sun, 23 Jul 2017 19:33:55 GMT https://svn.boost.org/trac10/ticket/10041#comment:1 https://svn.boost.org/trac10/ticket/10041#comment:1 <ul> <li><strong>owner</strong> changed from <span class="trac-author">ebf</span> to <span class="trac-author">Antony Polukhin</span> </li> <li><strong>status</strong> <span class="trac-field-old">new</span> → <span class="trac-field-new">assigned</span> </li> <li><strong>milestone</strong> <span class="trac-field-old">To Be Determined</span> → <span class="trac-field-new">Boost 1.65.0</span> </li> </ul> Ticket Antony Polukhin Sun, 23 Jul 2017 19:37:59 GMT https://svn.boost.org/trac10/ticket/10041#comment:3 https://svn.boost.org/trac10/ticket/10041#comment:3 <ul> <li><strong>status</strong> <span class="trac-field-old">assigned</span> → <span class="trac-field-new">closed</span> </li> <li><strong>resolution</strong> → <span class="trac-field-new">fixed</span> </li> </ul> Ticket
