I think this is a bug... #lang racket (struct lyst (kar kdr) #:mutable #:transparent)
(define-struct liist (kar kdr) #:mutable #:transparent) (shared ([a (lyst 7 a)]) a) (shared ([b (make-liist 7 b)]) b) produces (lyst 7 #<undefined>) #0=(liist 7 #0#) In other words, you have to use define-struct and get the make-blah constructor in order for shared to work. Please tell me that's not how it's supposed to work... Todd _________________________________________________ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/users
