My first code in clojure

I've finished reading Javascript The Good Parts. Yesterday a co-worker said to me that I could learn some functional language, He recommend to me Clojure son I've just started with Programming Clojure and this is my first little program:

(defn average [numbers]
 (/ 
 (apply + numbers)
 (count numbers)
 )
)

(println 
 (average [1 2 3 4 5])
)

When I was writing this little piece of code, I've remember when I was at university and I studied Lisp in IA signature.
