You may use reduce, as follows: (let [r (java.util.Random.) f (fn [el] (.nextBoolean r))] (def pred f))
(reduce (fn [m el] (let [k (pred el)] (assoc-in m [k] (conj (m k) el)))) {true [] false []} (range 10)) Thanks -- You received this message because you are subscribed to the Google Groups "Clojure" group.
