You'd need to generate a suitable function definition using a macro.
E.g.,
(defmacro def-my-map-fun [name m]
`(defn ~name
~(str "arg1 must be one of " (keys m))
[~'arg1]
(println ~'arg1 ~m)))
user=> (def-my-map-fun foobar {:foo :bar})
#'user/foobar
user=> (doc foobar)
-------------------------
user/foobar
([arg1])
arg1 must be one of (:foo)
nil
user=> (foobar 5)
5 {:foo :bar}
nil
Now's the moment when someone shows a better way ;)
