You actually don't need `map`, you can easily implement that using `reduce` too ;)

Nobody needs reduce, you’re just making code make less sense. If you’re using reduce when map works you’re just a masochist.

I'm well aware of that, but I don't think that's a good idea.

There is utility in communicating whether you're working with a catamorphism vs a homomorphism. Code is written for humans, after all.

Of course, that wasn't meant seriously. That's why i like `for_each` (or `iter` or whatever it's called) as 'third' function too, because it makes it clear you're doing side-effects.
