Rvalue references and Move semantics are a major C++11 feature that can significantly speed up code by reducing unnecessary copies. The STL has been updated to use this new feature when a c++11/0x compiler is used (e.g. gcc 4.6) I stumbled across this ticket : https://svn.boost.org/trac/boost/ticket/1841 which discusses the addition of move semantics to boost::optional. Is there any news on when the boost::optional library will support move semantics? I am primarily interested in using this library with a c++11/0x compiler (e.g. GCC 4.6). -- View this message in context: http://boost.2283326.n4.nabble.com/Status-of-move-semantics-with-boost-optio...
