;;;; 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. ;;;; Note that the MOP is not in a supported state. Package issues ;;;; (both MOP/SB-PCL and CL/SB-PCL) have yet to be resolved, and ;;;; there is likely to be missing functionality. However, this seems ;;;; a good a way as any of ensuring that we have no regressions. (defpackage "MOP-TEST" ;; eventually, we might want "MOP" as well here.
