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

26 Dec 2014

      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 <boost/move/adl_move_swap.hpp>
namespace boost
{
  template<class T1, class T2>
  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?
