Hi Herman,

Not sure, do you have an example on how to trigger it?

You shouldn’t rely on the return value of ‘info’, ‘warning’, etc.:
they’re not specified (that’s generally the case for procedures called
for side effects only).

So I’d recommend:

  (begin
    (info …)
    (values #f #f))

(You don’t even need ‘begin’ in this context.)

The other patches LGTM, though perhaps ‘tests/guix-style.sh’ could be
augmented a bit to cover the new cases?

Thanks,
Ludo’.
