I've been learning it for a couple of weeks. It is humbling as an experienced dev to find something quite straightforward (parens-whining aside, Clojure is a small & simple language), yet not have a clue how to approach problem-solving with it.
It does take me a long time to get there though. It's kicking my arse to be honest. Which is fine, as it means I'm learning - far more enlightening than frustrating.
