I'll always admire clojure. Loved the simplicity and philosophy, and I wrote a few toy projects. Unfortunately I felt like I could never really take advantage of the power of clojure or do real work in it because I didn't know or have a history with Java. It always felt like clojure was for enlightened Java or JS programmers, and I didn't want to learn Java and clojure at once so I was stuck in beginner land.
