Agreed. I really hope that Python 3.0 applies Raymond Hettinger's
suggestion "Improved default value logic for Dictionaries" from
http://wiki.python.org/moin/Python3%2e0Suggestions
This would allow you to make the setdefault() call only once, instead of
on every lookup:
class meh(dict):
def __init__(self, *args, **kwargs):
super(meh, self).__init__(*args, **kwargs)
self.setdefault(function=meh)
