The start/stop/step sound like they might be nice. But that wouldn't give you a length, since you never know when an iterator will be exhausted.  I feel like `len(islice(it, 1, 1_000_000))` telling you the "maximum possible length" is more a danger than a help.

I think islice should implement __length_hint__, though. As of 3.8.5 it doesn't.
