With C++11, the reason is to make 'clone' explicit.
(That said, maybe there could be a better way how to achieve this, maybe make copy-constructor explicit would work too, but addition int parameter is sort of legacy).

Thank you.
Explicit copy-constructor doesn't force to call "clone" for some reason.
Maybe, it makes sense to make pick/clone optional, and let compiler auto-generate default copy constructor? This legacy move semantics doesn't seem to have much sense when compiler already does good job moving temporary data for you. You still will be able to call "pick". Typing code which is not really necessary is very annoying ...

Thanks.
