Well, if you want to set a slot explicitly using the set! form, and this is a good way to access a slot, you can use an accessor (which internally is a pair of a getter and a setter):
(define-class a () (x #:accessor x)) (define o (make a)) (set! (x o) 1) (x o) -> 1 I guess you already know that you can *also* reference this slot using: (slot-set! o 'x 2) (slot-ref o 'x) -> 2 I should add that the accessor way fits well with GOOPS' (and CLOS') basically rather simple concept of having objects and then generic functions operating on them (an accessor is a generic function). Generic functions, in turn, fit with how some Scheme procedures accept different types of arguments and can dispatch to different actions on them.
