[racket] the typed Values restriction

If you want the continuation-passing-style version, you'll need to
explicitly handle the multiple-ness of multiple values:

#lang typed/racket

(: my-force (All (A ...) (-> (-> (Values A ...)) (Values A ...))))
(define (my-force x) (x))

(ann (my-force (lambda () (values (void) (void)))) (Values Void Void))
