Simple macro question

[Ergus]

Hi:

Playing with macros to generate function I got an problem I am not sure
how to solve or why is it an issue

In the following minimal code:

==============================

;;; test.el --- test editing -*- lexical-binding: t; -*-

;;; Commentary:

;;; Code:

(defvar test-commands-list '(A B C)
  "List of replaced functions.")

(defmacro test-def ()
  "Doc def."
  `(eval-and-compile ,@(mapcar (lambda (com) nil) test-commands-list)))

(test-def)

(provide 'test)
;;; test ends here

==============================

This code shows an error like:

Symbol’s value as variable is void: test-commands-list

in this line: (test-def)

I can't use test-commands-list either in this way or as an input if I
define the macro as:

(defmacro test-def (commands-list)
...

(test-def test-commands-list)

In this second case I get: wrong arguments sequencep test-commands-list

Is this intended?
