This defines the proper interface for all the classes with "Iterator" in their
name. None of them are actually iterators in terms of the Python protocol
`Iterator`, as they are expected to support `__len__` and __getitem__`. They're
the closest to the `Sequence` protocol, but without the support for slicing.
