;;;; To test the IGNORE/IGNORABLE behavior in CLOS, run COMPILE-FILE on
;;;; this file and look at the output (warnings, etc.).
;;;;
;;;; (In sbcl-0.6.8.25, the handling of IGNORE and IGNORABLE in
;;;; DEFMETHOD forms was rewritten to systematize the old PCL behavior.
;;;; Now all required variables are IGNORABLE by default.)
;;;; 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.
