Does the following look OK?

                                  ;; Use a closure here rather than
                                  ;; just `lazy-handler-dispatch' so
                                  ;; that lookup of
                                  ;; lazy-handler-dispatch's value is
                                  ;; deferred until a throw occurs.
                                  ;; This means that if code executed
                                  ;; in the REPL just above set!s
                                  ;; lazy-handler-dispatch, the new
                                  ;; value will be used to handle the
                                  ;; next throw from the REPL.
                                  (lambda args
                                    (apply lazy-handler-dispatch args))))
