I think islice should implement __length_hint__, though. As of 3.8.5 it doesn't.
And it could support __len__, and raise an Exception when the underlying iterable doesn’t support it.
I know that itertools needs to support arbitrary iterable, but I do wish it provided more Sequence features when it could.
islice, for instance, could support negative indexes when it is wrapping a Sequence.
