The #(println %) procedure takes only one argument (because you only
have that one % in there) and you are applying it to two, namely 2 and
3.
You are effectively trying to do (#(println %) 1 2).
Maybe try this instead:
(apply println [2 3])

Because the binding-form goes before the key when you use map-binding
forms, and a keyword (:coin) cannot be used as a binding-form.
