Description

I would like the grouped functions to provide an Iterable instead of an Iterator to the user, e.g. for the reduce method of GroupReduceFunction.

We had a discussion about this previously (I couldn't find the respective issues/list threads right now) and the result was in favor of the change.

We never got around to really push for it, because of the API break. With the renaming, it should be less of an issue.
