Comment (by nthiery):
Good point. To avoid having both `__iter__` and `__list__` you can just
do:
{{{
def __iter__(self):
return iter(self.group_generators())
}}}
Note the use of `iter` rather than `for ... yield` (should be faster).
Also, default list method will already raise an error if the set is in
`XXX.Infinite()`.
Thanks!
