One main goal of functional programming is writing less error prone code. When mapping a function over a sequence there's no way to get an off by one error, or any other bug associated with typical for loop.

Not a lot of aspects of functional programming are tied to the code is data idea (formally called homoiconicity). However when writing Clojure, the user is actually inputting Clojure data structures. Something I've noticed is structural navigation inside the editor has beneficial. I can edit Clojure code so much faster than any algol-family (C-like) language I've used. And while I find it important to spend more time thinking than typing, it's easier for me to stay in flow when the code is so malleable.
