You're right, I said it wrong (the last part, not the `Copy` being irrelevant part). There's no need to add to the language the ability to move (obviously it has that), but perhaps there's a need to add the ability to not move certain arguments by default, for convenience. I wouldn't want to see generic code littered with explicit .clone()'s all over the place.
