Clojure Flip

Recently, I found myself in need of a flip function in Clojure. Since I could not find anything in the official documentation, Stackoverflow, or Freenode, I came up with this:

(defn flip [f]
  (comp (partial apply f) reverse list))

Its behavior can be described like this (assuming Midje):

(facts "about flip"
  ((flip -) 1 2) => 1
  ((flip /) 1 2) => 2
  ((flip >) 1 2) => true
  ((flip str) 'foo 'bar 'baz) => "bazbarfoo")

Please, let me know in case you have a simpler solution ;)
