Clojure supports functions with multiple arities (http://clojure.org/
functional_programming).
Assuming you don't actually care if you call the function with a
vector, you can do something like this:
(defn sum
([] 0)
([acc & r]
(if (nil? r)
acc
(recur (+ acc (first r)) (rest r)))))
Not sure if that is precisely what you want or not.
