The template part is not necessary due to ADL but you should make such
function available via ordinary lookup (i.e. boost::move) so you are back to

How about the following non-intrusive yet sufficient implementation:

template <class U>
move_ptr<U> move(move_ptr<U>& p)
{ return 1 ? p : move_ptr<U>(); }

It actually works but I'm just kidding because not all compilers agree on
