Equivalent code like this:
====================
;;; test.el --- test editing -*- lexical-binding: t; -*-
;;; Commentary:
;;; Code:
(defvar test-commands-list '(A B C)
"List of replaced functions.")
(defun test-fun (com)
"Testfun with COM."
nil)
(defmacro test-def (thelist)
"Doc def."
`(progn ,@(mapcar #'test-fun thelist)))
(test-def (A B C))
(provide 'test)
;;; test ends here
============================
Says that: Symbol’s function definition is void: test-fun
