This is essentially getting back to what Armin was saying.. if iterators act more like lists, they will be easier to user and will open up some new doors for optimization potential. Adding a way to get the length of some iterators essentially makes them list-like or tuple-like.
Agreed. I don't mind the crux of Armin's idea, I was reacting more to applying such optimizations to enumerate() in particular. Given sufficient clarification like the above, it'd be easier to swallow.
