Is there any Clojure built-in function that just returns the value being passed to it? The equivalent of
(defn just-val [x] x)
?

It's an interesting question. Is this for parameter checking?

i need to either return a value untouched or to apply a function to it, so i can pass the function to apply that's either a function doing something or (identity), as learned by ollb answer :)
