I'd like to change the result of a 0-arity function, but I need help
crafting the right magic spell. Here's my attempt.
#lang racket/base
(struct wrap (vals)) ;; Wrap a list
(define (create) '())
(define create-wrap
(impersonate-procedure create
(lambda ()
;;(values)))) ;; -- this will run, but it doesn't wrap the result
like I'd like.
(values (lambda (r) (wrap r))
(values)))))
(create-wrap) ;; Error! result arity mismatch: expected 1, got 0.
