If you already have a list in Erlang, you can use map and the foldl/foldr reducers. But there's no general for-loop. You're expected to use tail recursion.

Also tbh, I don't like reduce either. I agree with that article posted on HN a while back about devs not liking reduce. Just want to insert into my list or whatever, not have to check how exactly reduce works in this particular language.
