Clojure partial right

Question

I have the following function

(defn fun [a b] (str a b))

(fun "1" "2") ;; --> "12"

Thanks to (partial) I can turn it into (fun b) and have a fixed a

(def fun2 (partial fun "1"))

(fun2 "2") ;; --> "12"

Does clojure have something like (partial-right) or a way to rearrange the arguments of a function so that instead of having a fixed a I can have a fixed b and hence have the function (fun a)?

Thanks

Answer 1

(defn partial-right [f & args1]
    (fn [& args2]
        (apply f (concat args2 args1))))

But ask yourself...why isn't this already part of the standard library? Is it perhaps that other people have wandered this way and it turned out badly?
