For those who have attempted to use a functional programming language (Haskell, Clojure, OCaml, F#, Elm, …) and failed to have it stick - What went wrong? What roadblocks did you run into?

For me (tried scala professionally in ~2015) it was: - Too much fanfare to do trivial things - sub-par tooling (sbt wasn’t that great) - libraries that were their own world and had sub-par documentation, often implicitly assuming you already knew how to use the library I have no hard feelings for scala, it’s just not my thing. At the time i also kinda lost the interest for functional languages because i tried golang and it was incredibly more practical, productive and fun to write.
