Anything that gives the target object the state the source object had and is cheaper than a copy is a successful move, really. That is what a move ultimately is: an optimization of copying.
I never liked that characterization. If move were an optimization of copy it would have all the semantics of copy... but it doesn't. In a move, the source object state becomes indeterminate. -- Dave Abrahams
