Hmm. Modifying an object while iterating over it isn't a great idea, ever:
I wouldn't say never. Algorithms that calculate some kind of
transitive closure can be expressed rather neatly by appending
items to a list being iterated over.
You can accommodate that kind of thing by writing the iterator
like this:
def __iter__(self):
i = 0
while i < len(self):
yield self[i]
i += 1
