Sorry. I hit the wrong button and sended an incomplete mail.

iterators
 - It would be convenient to have a reverse iterator for lists which
would also allow to iterate backwards.
 - class with special iterators/iterables that can iterate Forward /
Backwards, skip elements, iterate through enumerated list, generators

I have most of this already added to libgee however I want to discuss
this before I release a patch or anything.
