I don't thik every parent with iter sould be in enumerated. Enumerated means that there is some cononical enumeration and that as a consequence, list, __iter__, __getitem__ have to return their result with a consistent ordering. Nothing is currently implemented, but I had in mind that morphism of enumerated sets should preserve the canonical enumeration... > Also, I dislike .list() returning a Python list.

Maybe call it enumerate() > with an alias list()? I like that but I would like for more vote before setting it as a rule.
