It doesn't help that fold/reduce often have different orders depending on the ecosystem. Every few months when I have a reason to reach for `fold` in nutshell I forget that it has the next element as the first arg instead of the second, which is what I'm used to from Rust. I guess I should just be happy I don't need to specify which direction I want like in OCaml.
