I can potentially see a situation like this:
auto fun(T)(return ref T x)
Where the auto deduces to something that couldn't possibly match T or any piece

That is addressed by the DIP, it is specifically allowed that a 'return ref' can
be used even when the pointer cannot be coerced into the returned ref.
This is so that the 'return ref' can refer to a container that completely owns
its contents, and this ownership can thus be transferred to the output.
