Some of the Structure and Interpretation of Computer Programs exercises in Clojure.
This is not a particular efficient way to learn Clojure. You can give it a try if you want to, but don't say I recommended it.
I did this for a while, until something even more interesting demanded my attention. Wasn't very long - I never made it past chapter 1.
I don't really think there is any material available here that is all that usefull or interesting for anyone. The time measurement results in AnswerToExercise_1_22.clj may be an exception, persumably showing the Java JIT in action.
