;;;; miscellaneous side-effectful tests of the MOP

;;;; This software is part of the SBCL system. See the README file for
;;;; more information.
;;;;
;;;; While most of SBCL is derived from the CMU CL system, the test
;;;; files (like this one) were written from scratch after the fork
;;;; from CMU CL.
;;;;
;;;; This software is in the public domain and is provided with
;;;; absolutely no warranty. See the COPYING and CREDITS files for
;;;; more information.

;;; this file tests that it is not possible to add an
;;; optimization-invalidating method to #'(SETF
;;; SLOT-VALUE-USING-CLASS).  If a way is found to preserve the
;;; optimization, or if the optimization is deemed to be invalid, then
;;; this test can go away.
