Suppose we had the following:
(defn stupid-wrapper [f args]
(. js/console log args)
(let [ans (f args)]
(. js/console log ans)
ans))
It basically logs the arguments + return value on every function call.
Now, suppose I wanted to do this to _functions that already existed_ .
Is there a way to do this?
I.e. someone already wrote:
(defn foo [ ... ] ... )
now, I want to do :
(black-magic! foo)
;; and have this "wrap" the foo function. Is there a way to make this work?
Thnaks!
