classes and __iter__

[david.garvey at gmail.com]

Chris,

Both a list and dict are both iterable.  I get a python dictionary object
of both iterables.;) It is nice... but I don't know if this is good form?
Should I be asking the duck question here?
>>> print helo.__dict__
{'keylist': [0, 1, 2, 3, 4, 5, 6, 7, 9, 10, 11, 12, 13, 14, 15, 16, 17, 20,
