but i have no more access to previous definition that is not keep in
the overloaded procedure,see #!null values:
here are my two attempt codes:
(define (create-overloaded-existing-operator orig-funct funct
pred-list) ;; works for associative operators
(display "create-overloaded-existing-operator")
(display " : pred-list = ") (display pred-list) (newline)
(define old-funct orig-funct)
(define new-funct (lambda args ;; args is the list of arguments
;; (display "new-funct: new-funct = ") (display
new-funct) (newline)
;; (display "new-funct : pred-list = ") (display
pred-list) (newline)
;; (display "new-funct : args = ") (display args) (newline)
(define nb-args (length args))
;;(display "new-funct : nb-args = ") (display nb-args) (newline)
(cond ((check-arguments pred-list args) ;;(begin
;;(display "new funct :calling:")
(display funct) (newline)
(apply funct args));;)
((> nb-args 2) (new-funct (car args)
(apply new-funct (cdr args)))) ;;
op(a,b,...) = op(a,op(b,...))
(else
;;(begin
;;(display "new funct :calling: ") (display
old-funct) (newline)
(apply old-funct args)))));;)
(display "funct: ") (display funct) (newline)
(display "orig-funct: ") (display orig-funct) (newline)
(display "old-funct: ") (display old-funct) (newline)
(display "new-funct: ") (display new-funct) (newline)
;;(replace-operator! orig-funct new-funct)
new-funct)
(define (create-overloaded-existing-operator2 orig-funct funct
pred-list) ;; works for associative operators
(let ((old-funct orig-funct))
(letrec ((new-funct (lambda args ;; args is the list of arguments
;; (display "new-funct: new-funct = ") (display
new-funct) (newline)
;; (display "new-funct : pred-list = ") (display
pred-list) (newline)
;; (display "new-funct : args = ") (display args) (newline)
(define nb-args (length args))
;;(display "new-funct : nb-args = ") (display nb-args) (newline)
(cond ((check-arguments pred-list args) ;;(begin
;;(display "new funct :calling:") (display funct) (newline)
(apply funct args));;)
((> nb-args 2) (new-funct (car args)
(apply new-funct (cdr args)))) ;;
op(a,b,...) = op(a,op(b,...))
(else
;;(begin
;;(display "new funct :calling: ") (display
old-funct) (newline)
(apply old-funct args))))))
(display "funct: ") (display funct) (newline)
(display "orig-funct: ") (display orig-funct) (newline)
(display "old-funct: ") (display old-funct) (newline)
(display "new-funct: ") (display new-funct) (newline)
new-funct)))
with define or let and letrec it give the same #!null ????
