Some folks on comp.lang.python have been pushing for itertools to include a flatten() operation. Unless you guys have some thoughts on the subject, I'm inclined to accept the request.
Rather than calling it flatten(), it would be called "walk" and provide a generalized capability to descend through nested iterables (similar to what os.walk does for directories). The one wrinkle is having a stoplist argument to specify types that should be considered atomic eventhough they might be iterable (strings for example).
