help understanding how map works
I am learning Clojure and have installed Clojure 1.2.0 in an Ubuntu 11 box. While playing with the map function I ran into some behavior I don't understand. I tried to use map to change a list of strings into a list of vectors of strings, something like: (A B C) = ( [ A] [B] [C]) Inlining the function does not work: user= (map #([ % ]) '(A B C)) java.lang.IllegalArgumentException: Wrong number of args (0) passed to: PersistentVector user= But defining an external function does: user= (defn wrap [ x ] [ x ] ) #'user/wrap user= (map #(wrap %) '(A B C)) ([A] [B] [C]) user= can someone explain to me why this is the case?
