The nameReduceIfis quite confusing to me. Something likeStopIf or StopWhen would make a lot more sense. Iterators.takewhile is a related concept, but the predicate has opposite polarity, and as was pointed out on Zulip, handles the final element differently.
I don't think there's a direct connection between ReduceIf and e.g. Base.reduce, which is like "fold".
