Bad ergonomics and poor naming do it for me. I learned Haskell, OCaml and some Idris just fine, but trying to write non trivial code in ATS was rage inducing. The same goes for J: I had no trouble with APL or K, but J was on another level. The one I took more time to grok at a fundamental level was Prolog, and I still consider myself a newbie.
