Quuxplusone added a comment.

No matter how it works internally, I think that (nearer the end of the process) 
someone should insist that you add some Clang tests to verify e.g.
  Widget&& a = static_cast<Widget&&>(Widget());  // is lifetime-extended, but
  Widget&& b = std::move(Widget());              // is not

and whatever other corner-cases people can think of. That is, these may turn 
into not-a-function-calls internally, but they'd better continue to behave 
//observably// as if they were function-calls.
