This is a really just an awkward way of doing `void foo(@rvalue 
ref S s)`.

At this point you have essentially admitted rvalue ref in the 
language but you're fighting to keep it hidden from the user as 
much as possible. I personally don't thing rvalue ref is that 
much dangerous to be kept away from the programmers hand. Hiding 
rvalue ref under auto ref is simply discouraging people from 
using it.
