If it were possible that the interpreter iterating over a dictionary could cause the dictionary to change size then I suspect that this would be a rich source of bugs to mine. :-) It would be great if we could make it a documented, enforced invariant that the interpreter reading a dictionary never produces a side effect visible to the interpreter.
