Hmm, do you mean if you want ``x is not y`` but ``x == y`` for interned string
x and some string y?

But I'm not sure that that's what the OP's up to. E.g. you could have a
container mapping symbols to other things -- possibly also symbols or further
containers. You then might want to make a deepcopy of it. You presumably still
want the symbols to be the same symbols in the copy (so that you can make use
of the identity), so asking whether ``deepcopy(symbol) is symbol`` doesn't
seem that unreasonable to me (is it?).
