Is this a bug or a feature?
The bug was me being so excited about the new construct (I pushed in someone else's work, can't recall who now, maybe Fredrik Lundh?) that I didn't consider that leaking the loop variable out of the list comprehension was a bad idea. Think of the Py3 behavior as one of those "corrections" to things which were "got wrong" in Python 1 or 2. :-)
