Hi
If I apply the following function to 4 and 6
(defn arith [x y]
(map (fn [op] [(op x y) `(~op ~x ~y)]) [+ - / *]))
I'd like to get a result of the form
([10 (+ 4 6)] [-2 (- 4 6)] ...)
but instead I get something like
([10 (#core$_PLUS_ clojure.core$_PLUS_@4f6de641 4 6)] ...

that the result of ('+ 3 5) is 5. I'm not sure what I would have
expected (maybe an error?) but it wasn't the third item of the list.
Is there any reason for this?
