There are also comments worrying that an abstract implementation would be horribly slow -- but so what?
Alex Martelli posted some stats (for dicts, I think) showing that (even today) clear was slower than just creating a new object. It still makes sense if you care about the "is" relation
Since you are keeping "pop", the abstract implementation can at least approximate iteration.
