Question

I wonder if there is an idiom in Clojure for combining several one argument functions into a new function accepting a vector. The new function should apply the first function to the first argument and so on.

I think this is useful in a number of situations. For example, you might want to transform x, y and z coordinates of a point using simpler unidimensional functions.

I would implement by myself as follows but I’m afraid it should already exists something similar in the standard API.

(defn vector-comp [& fns]
  (fn [avect]
    (vec (map #(%1 %2) fns avect))))
