I think the designers of Clojure intend it as a language for experts. In many fields non-experts can make nice progress, but they need to be aware that they may stub their toes. So, pull requests, code reviews, pairing, etc. are available and well established as means for helping people make the transition from beginner to journeyman (person) and beyond. If I know how to walk, but not how to ride a bike, I hardly think others should be denied nice bike routes.
