How is this:
#lang racket
(define graph%
(class object%
(field ((n nodes) '()))
(public (get get-fields))
(define/public (all) (get))
(define (get) n)
(super-new)))
(define graph (new graph%))
(define fields (get-field nodes graph))
(equal? (send graph get-fields) fields)
(equal? (send graph all) fields)
