I really like Clojure, it's the language that finally made FP "click" for me. It was my go to for hobby/side projects for quite a while.

Dynamic typing is why I eventually switched. Haskell scratches the same itches that Clojure did, but the compiler and type system are immensely helpful, and keep saving me from tripping over my own feet.

Common Lisp is my go-to language, but I also like Haskell and Clojure. To me, Haskell is a Lisp, and supports REPL driven development.

Somewhat off topic: My problem with Haskell is that every time I've tried to read the documentation, I've felt like I needed a PhD in type theory to understand all of the terminology. As a practitioner (not a researcher), I just want to know how to do things, but the documentation has always been a roadblock to me. So, after a number of attempts at learning to use Haskell, I've decided its not for me. Not because of the language itself, but because of the traditions around it.

This. I think I understand the basic concepts, but you get a first big slap with doing your first curl to some other service. Ergonomics of the libs is often times horrible. You are in this constant loop, oh I can't do this I need algebraic derationalizer to align those types. Several hours later your curl request works. You start looking at wall to decompress. Curl is a pretty good example its a complexity that has been made super easy in a lot of languages.

I am very much waiting for some "extremely" constraint subset/flavour of Haskell that gets some adoption(I do not think I am alone in this lobby). No crazy stuff, no "just read the types", no "its just a small extension". But I also know that it is not really feasible without breaking the IO enforcements.
