what use is having access to the constructor without access to the field getters and setters.
One possible answer to this is that you can match on a structure with just its constructor in scope:
;; s.rkt #lang racket (provide foo) (struct foo (bar baz)) ;; other.rkt (require "s.rkt") (match (foo 1 2) [(foo a b) (+ a b)]) ;; => 3 ;; note that neither foo-bar nor foo-baz are in scope Regards, Tony ____________________ Racket Users list: http://lists.racket-lang.org/users
