Subject: exporting procedure else now breaks case's else clause
Date: Sun, 14 Sep 2014 11:42:01 +0200 [thread overview]
Message-ID: <87y4tmilna.fsf@drakenvlieg.flower> (raw)
Hi,
In stable-2.0, this works
(define-module (case) #:export (else))
(define (else ast) (if (> (length ast) 3) (cadddr ast) #f))
(define t 't) (case t ((t) #t) (else (eq? t 't)))
with latest master it breaks as soon as else is added to the exports
list:
;;; /home/janneke/vc/verum/development/gaiag/module/gaiag/case.scm:9:31: case: invalid clause in subform (else (eq? t (quote t))) of (case t ((t) #t) (else (eq? t (quote t))))
language/cps/reify-primitives.scm:75:11: In procedure #<procedure 2477220 at ice-9/boot-9.scm:509:12 (expr clause clauses)>:
language/cps/reify-primitives.scm:75:11: Syntax error:
/home/janneke/vc/verum/development/gaiag/module/gaiag/case.scm:9:31: case: invalid clause in subform (else (eq? t (quote t))) of (case t ((t) #t) (else (eq? t (quote t))))
Bug or feature?
Greetings, Jan
