Maybe I didn't read that carefully enough, but it looks like "ordered" means the dict records come out in the same order you inserted them in. That is if you insert B,A,D,C in that order, you get them out in that order. I would have thought an ordered dict meant you get A,B,C,D, which seems a lot more useful. Red-black trees as described at the bottom of the page are a good way to get A,B,C,D. They also make it simple to have "persistent" or "functional" dictionaries, which I've written about a few times before. -- http://mail.python.org/mailman/listinfo/python-list
