Just take an idea from Haskell (as usual!). Function 'flip' returns a function taking its first two arguments in order opposite the given function:
user> (defn flip [f] (fn [a2 a1 & more] (apply f a1 a2 more))) #'user/flip user> (- 10 2 3) 5 user> ((flip -) 2 10 3) 5 user> ((partial < 2000) 1000) false user> ((partial (flip <) 2000) 1000) true -- You received this message because you are subscribed to the Google Groups "Clojure" group.
