Hi!
This is a much-stripped-down version of a `define-values' macro,
exposing what seems like a psyntax bug:
% cat guile-psyntax-temp-set-issue.scm
(define-syntax define+set!
(lambda (form)
(syntax-case form ()
((_)
(with-syntax (((mutable-id) (generate-temporaries '(id))))
#'(begin
(define mutable-id #f)
(set! mutable-id #t)))))))
(define+set!)
% guile guile-psyntax-temp-set-issue.scm
;;; note: auto-compilation is enabled, set GUILE_AUTO_COMPILE=0
;;; or pass the --no-auto-compile argument to disable.
;;; compiling /home/rotty/tmp/guile-psyntax-temp-set-issue.scm
;;; WARNING (module system is booted, we should have a module #{ g65}#)
;;; compiled
/home/rotty/.cache/guile/ccache/2.0-LE-8-2.0/home/rotty/tmp/guile-psyntax-temp-set-issue.scm.go
Note the WARNING line; it seems during expansion something goes wrong
wrt. to modules -- it'd be really nice if some psyntax guru can have a
look at this.
Regards, Rotty
