Thanks, I was probably asking for the wrong thing. I meant something
like the code describe-function that shows the function symbol.

I ended up stealing that code:


;;;###autoload
(defun ourcomments-indirect-fun (fun)
  "Get the alias for function FUN if any."
  ;; This code is from `describe-function-1'.
  (when (and (symbolp fun)
             (functionp fun))
    (let ((def (symbol-function fun)))
      (when (symbolp def)
        (while (and (fboundp def)
                    (symbolp (symbol-function def)))
          (setq def (symbol-function def)))
        def))))
