The new ‘unbound-variable’ warning in 3.0.5 has false positives, as in
this example:
--8<---------------cut here---------------start------------->8---
$ cat /tmp/unbound.scm
(use-modules (srfi srfi-35))
(condition (&message (message "oh no!"))
(&serious))
$ guild compile -Wunbound-variable /tmp/unbound.scm
/tmp/unbound.scm:3:0: warning: possibly unbound variable
`make-compound-condition'
