Most of my Clojure WTFs were not related to the language itself, but rather the tooling. This was years ago, but everyone used to say, "Before diving into Clojure, you should really learn emacs and all these other things first." I'm glad I ignored them and sputtered along in a text editor while learning the basics of the language, because I would've otherwise burnt out.
With apps like Light Table now available, maybe beginners have an easier ramp these days.
