In Python 2.2, you can loop directly on a dictionary, skipping the
costly step of extracting its list of keys with a .keys() call -- so,
if you're using Python 2.2, no TypeError would be raised here.

This is just a part of the benefit you get from Python 2.2's new
arrangement for iterators -- ability to iterate directly on such
objects as dictionaries and files.  Handy, speedy AND readable...!
