The only specification is that len(ob) calls ob.__len__ and that ob.__len__ should return an 'integer >= 0'. (Adding side effects goes beyond that spec.) I agree that a detectable internal in list is not a bug. Unless there is a realistic performance enhancement in caching the result of the first call, this issue should be closed. |
