I have 0 beef with it being the TypeError as long as the exception chain is kept intact, especially since PY3 makes it possible. With current behaviour heisenbugs would produce some serious hair pulling, until one figures out that it is actually the __iter__ raising an exception.

With that in mind, take an object implementing the __iter__ dunder correctly 999,999 times out of a million. Is it not iterable?

Unfortunately I lack the experience with CPython C API to do something about this. Tests on the other hand I suppose I could manage, if a consensus on the behaviour can be reached.
