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))))

Regards,
        Neil
