Terry J. Reedy added the comment:

Stephen, your class, or rather instances thereof when initialized with a sequence, follow the old iteration protocol. You might call them iterators in the generic sense, though I cannot remember whether we used 'iterator' much before the introduction of the new and now dominant iteration protocol. I am sure 'iterable' was introduced with the new protocol for objects with .__iter__ methods that return iterators, which in this context means an object with a .__next__ method and excludes .__getitem__ objects.

It would have been less confusing is we had disabled the old protocol in 3.0, but aside from the predictable confusion, it seemed better to keep it.
