> 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.
