Examples of elegant, concise code in Clojure

Question

I'm looking for enlightening examples of concise and elegant code in Clojure - mainly to learn new techniques and improve my own style.

Can you offer any nuggets of pure genius?

Answer 1

Basically everything Nurullah Akkaya posts:

Definitely some of the most imaginative Clojure examples around. Don't blame me for all the time you'll spend reading his stuff... ;-)

Answer 2

This is fun:

(= (sort "eleven plus two") (sort "twelve plus one"))

This evaluates to true because "eleven plus two" is an anagram of "twelve plus one"

More fun than useful.

Answer 3

Ring is an excellent example - very idiomatic and elegant code there.
