Hi,
There is also a defnk macro by Rich, which allows
easy definition of keyword args for functions.

Thanks all, Clojure list is the best.

And you can use destructuring to add support for defaults value:
(defn my-f
you can also use map destructuring.
(defn x [{:keys [a b c]}]
[a b c])
user=> (x {:a 1 :b 2 :c 3})
[1 2 3]

Is there anything in core or contrib for parsing arguments to a
function? Since Clojure fns don't support optional args or even keyword
args, is there a standard set of helpers functions to do this? I looked
around but I didn't see anything obvious.
