ReIterable and Collection are different concepts.
- ReIterable just implements __iter__ but promises certain semantics.
- Collection implements __iter__, __contains__ and __len__.

If we had ReIterable I would probably decree that Collection inherits from it (practicality beats purity).

But I don't think ReIterable by itself would do much good; apart from a few "show-off" hacks, any reasonable ReIterable would also be able to implement __contains__ and __len__ easily.

And I would certainly call range() a Collection.
