Why? I can conceivably imagine that zip(iter1, iter2, truncate=5) would consume at most 5 elements from each iterable. It's not much of a stretch. It doesn't happen to be what's proposed, but it's a reasonable interpretation. (Though then the default would probably be truncate=None to not truncate.)
This was exactly my thought, that Chris wrote very well. I can easily imagine a 'truncate=5' behavior. In fact, if it existed, it is something I would have used multiple times. As is, I use islice() or a break inside a loop, but that hypothetical parameter might be a helpful convenience.
However, it is indeed NOT the current proposal or discussion.
Besides, "zip(iter1, iter2, range(5))" is the same length once you include the extra unpack, plus it works well with earlier versions. Cheers, Steve
