Comment (by Andrey Glebov <andrey458641387@…>):

 Note on the `libstdc++` implementation of `is_nothrow_move_assignable`:
 it actually also contains:
 {{{
 #!c++
   template<typename _Tp, typename _Up>
     struct is_nothrow_assignable
     : public __and_<is_assignable<_Tp, _Up>,
                     __is_nt_assignable_impl<_Tp, _Up>>
     { };
 }}}
 where `is_assignable<_Tp, _Up>` is implemented in terms of the intrinsic
 `__is_assignable(To, From)`.
 This shouldn't be an issue though since that intrinsic seems to be
 supplied by most compilers.
