Definitely something that would be nice.
But if we have/implement such a catcher, I'd like to have an annotation to say
"yep I really want to reuse this moved-from object".
Because sometimes the function will choose not to actually move from an
rvalue-ref, or the object knows to revert to a fully-reusable state, etc.
