I would like to see the following:
- sqlength should return maxsize if the actual value doesn't fit So that code will silently behave as though the rest of the sequence wasn't there some of the time? Can you elaborate on the rationale for this? I'm having trouble seeing how it's a good idea.
Yeah, it sounds more like behaviour I would expect from length_hint, not length.
In the bug tracker, Alexander mentioned the possibility of removing length and getitem support from range() objects in py3k, and implementing only length_hint instead (leaving range() as a bare-bones iterable). I'm starting to like that idea more and more.
Cheers, Nick.
