Okay, I'm confused. Is this the sort of code that would be unsafe (I
know it's contrived)?

(define (run)
    (display "Welcome to Gendanken")
          (lambda ()
              (display ">> ")
              (let ((input-exp (read)))
                (unless (equal? input-exp '(exit))
                   (lambda (k)
                      (if (equal? input-exp 'skip) (k '()) 'x))))
      ;enter the main loop
