[racket] how to get sandbox to drop errors

You're evaluating the (/ 1 0) before you make your evaluator. You have
to quote it.

The following works for me:

(define my-eval
  (parameterize ([sandbox-output #f]
                 [sandbox-error-output #f]
                 [sandbox-propagate-exceptions #f]
                 [sandbox-propagate-breaks #f])
    (make-evaluator 'racket)))
(my-eval '(/ 1 0))
