[boost] [core] A better boost::swap

Hi all, Ion Gaztañaga implemented a very good swap that used move emulation when possible and has all the features of boost::swap: http://www.boost.org/doc/libs/develop/boost/move/adl_move_swap.hpp I've tried to change default implementation of ::boost::swap to #include namespace boost { template BOOST_GPU_ENABLED void swap(T1& left, T2& right) { ::boost::adl_move_swap(left, right); } } All the tests of the Boost.Swap passed. Ion's solution looks better than existing boost::swap. Are there any reasons not to change the existing implementation of Boost.Swap to Ion's version? -- Best regards, Antony Polukhin
