Here http://www.boost.org/doc/libs/1_56_0/doc/html/boost/move_idp159681920.html it states: "This function provides a way to convert a reference into a rvalue reference in compilers with rvalue references. For other compilers converts T & into ::boost::rv<T> & so that move emulation is activated." But in I see: template <class T> inline typename ::boost::move_detail::enable_if_c < enable_move_utility_emulation<T>::value && !has_move_emulation_enabled<T>::value, T&>::type move(T& x) { return x; } Therefore shouldn't the above be: "This function provides a way to convert a reference into a rvalue reference in compilers with rvalue references. For other compilers if T is Boost.Move enabled type then it converts T & into ::boost::rv<T> & so that move emulation is activated, else it returns T &."
