This does it without using juxt: (defn supermap [fs & cs] (map apply fs (apply map vector cs))) With juxt it's as Meikel wrote: (defn supermap [fs & cs] (apply map (apply juxt fs) cs)) user=> (supermap [#(* %1 %2) #(* %1 %2 %2) + -] [1 2 3 4] [5 6 7 8]) (5 72 10 -4) -- You received this message because you are subscribed to the Google Groups "Clojure" group.
