If you want "really fast", there is the unchecked-math flag or the unchecked-* operations. You have "really fast, unsafe" -> "fast, safe" -> "slow, safe". Clojure chose the middle path. No one prevents you from deviating to the left or the right via unchecked-* or *'. Sincerely Meikel -- You received this message because you are subscribed to the Google Groups "Clojure" group.
