Hello, I am getting following warning from a guild compile:
warning: possibly unused local top-level variable `%foo?-procedure'
And I am not sure how to tackle it. This is my full source code:
(define-module (x)
#:use-module (srfi srfi-9)
#:export (<foo>
foo?
make-foo))
(define-record-type <foo> (make-foo) foo?)
When I try to compile it:
$ guild compile -W 3 -o x.go x.scm
x.scm:7:0: warning: possibly unused local top-level variable
`%foo?-procedure'
wrote `x.go'
I would (for obvious reasons) like to keep my compilation warning-free. I can
think of two approaches:
1. Export the %foo?-procedure
I think this would confuse downstream users, since they are not expected to
use it directly.
2. Mark the procedure as used
In C I could use `(void)proc;', is there an equivalent of that construct
in Guile?
Are there other options? How are you approaching it?
Thank you and have a nice day,
Tomas Volf
PS: I am not even sure why this warning happens, the `foo?' syntax transformer
is exported and *does* reference it (as far as I can tell from ,expand).
