The ability to introspect is basic to Python's design. Objects know their class, functions know their code objects, bound methods know both their underlying function, classes know their own class dictionary, etc. Should iterators know their iterable when there is one? There is or was a request for this on python-list, I believe, a few days ago. I suggested bad idea because a) iterator requirement is intentially minimal b) not all iterators have underlying object c) OP wanted to mutate underlying object (list) while iterating I did give a myiter class that would do what OP wanted. Mutation of the underlying iterable is a terrible idea. Imagine the confusion when multiple iterators are active on the same iterable. But I suspect I am preaching to the choir here.
