Really?  I have this:

--8<---------------cut here---------------start------------->8---
$ guix package -m ~/t.scm
guix package: error: failed to load '/home/ludo/t.scm':
/home/ludo/t.scm:1:0: /home/ludo/t.scm:1:0: In procedure module-lookup: Unbound variable: definieee
$ cat ~/t.scm
(definieee foo bar)
--8<---------------cut here---------------end--------------->8---

When ‘make-stack’ returns #f, that’s OK: it just means we won’t be able
to display a backtrace.

HTH,
