I've sat and thought about this for 20 minutes before deciding that no, it
isn't possible. One of the shortcomings of the move emulation, I'm afraid:
the return value must already be a temporary of the return type; getting it
from implicit conversion then blocks the implicit conversion to the mover
type.
