With C++11, the reason is to make 'clone' explicit.

We want to prevent this:

Vector<int> a, b;

a = b;

and force the user to write either

a = pick(b);

or

a = clone(b);

(That said, maybe there could be a better way how to achieve this, maybe make copy-construtor explict would work too, but addition int parameter is sort of legacy).
