I was going by this: "For certain functions, such as addition, they are the same, but that is because the addition function (+) itself 'reduces' its arguments." http://osdir.com/ml/java.clojure.user/2008-07/msg00237.htm The thread is somewhat older, but looking at the source for + it seems like this is still valid: user=> (source +) (defn + "Returns the sum of nums. (+) returns 0." {:inline (fn [x y] `(. clojure.lang.Numbers (add ~x ~y))) :inline-arities #{2}} ([] 0) ([x] (cast Number x)) ([x y] (. clojure.lang.Numbers (add x y))) ([x y & more] (reduce + (+ x y) more))) Michael -- You received this message because you are subscribed to the Google Groups "Clojure" group.
