I know that range(start,end,stride) will produce what I'd want from iter(slice(start,end,stride)), but wouldn't it be reasonable for a slice itself to be iterable?

Yes, only one obvious way and all that, but inside eg __getitem__ it seems to me that:

if isinstance(index, slice):
    for i in index:
        ... do stuff with i ...

is the obvious thing to do.

What if the start is positive and the end is negative? What values should i get?
