Examples of Clojure arity-overloading on functions like the following (taken from the cookbook):

(defn argcount
  ([] 0)                                ; Zero arguments
  ([x] 1)                               ; One argument
  ([ x &  args] (inc (count args))))    ; List of arguments

... use a form that doesn't seem to allow the functions of lower arity to simply call the functions of higher arity with some default values (that's a common idiom in Java). Is some other special form used for that ?
