Standard version or idiomatic use of (fn [f & args] (apply f args))

Question

Every so often I find myself wanting to apply a collection of functions on several collections of parameters. It\'s easy to do with map and a very simple function.

Answer 1

I personally think your first version is pretty clear and idiomatic.

Here's an alternative you might find interesting to consider however:

(map 
  apply 
  [- + *] 
  (map vector [1 2 3] [1 2 3] [1 2 3]))

=> (-1 6 27)

Note the trick of using (map vector ....) to transpose the sequence of arguments into ([1 1 1] [2 2 2] [3 3 3]) so that they can be used in the apply function.
