Hi, everybody! I got a question while I'm trying GOOPS, here is some example code pieces: ;;guile code (define-class () (cache #:init-form 0) (tt #:init-form 1 #:allocation #:virtual #:slot-set! (lambda (o v) (slot-set! o 'cache (cons v (slot-ref o 'cache))) );;end lambda #:slot-ref (lambda (o) #f) ;; ***FIXME: can I use generic "slot-ref" without re-define here?? .......... ;;guile code end ----------------------------------------------- Please notice the line with "***FIXME" .I know that the "slot-set!" and "slot-ref" must be re-defined under "#:allocation #:virtual", but can I find some approach that just re-define one of them? Maybe I'll need a modified(with overload) "slot-set!", but I need a generic "slot-ref" in some circumstance. I don't know how to do. If I called "slot-ref" in the re-defination of "slot-ref", that would be recursively infinite. How can I deal with this? Any help will be appreciated, thanks!
