Let me disagree. As stated before, I never used moveXXX in my code. That 
doesn't mean it is useless, but that you can definitively work with an 
abstraction without messing around with all possible « extensions ».

I'd argue that this is the key to successful abstraction : a solid core, 
a possibility for extension and knowledge of such extension being optional.
