1 ;;;; miscellaneous side-effectful tests of the MOP
3 ;;;; This software is part of the SBCL system. See the README file for
6 ;;;; While most of SBCL is derived from the CMU CL system, the test
7 ;;;; files (like this one) were written from scratch after the fork
10 ;;;; This software is in the public domain and is provided with
11 ;;;; absolutely no warranty. See the COPYING and CREDITS files for
12 ;;;; more information.
14 ;;;; Note that the MOP is not in a supported state. Package issues
15 ;;;; (both MOP/SB-PCL and CL/SB-PCL) have yet to be resolved, and
16 ;;;; there is likely to be missing functionality. However, this seems
17 ;;;; a good a way as any of ensuring that we have no regressions.

37 This is actually a test of vanilla CLOS, not the MOP; however, there isn't
38 a terribly easy way of testing this without it (FIXME: one would have to
39 construct a series of DOCUMENTATION methods, probably involving
40 CALL-NEXT-METHOD). However, since we're actually getting this wrong
41 currently, better put in a quick test in the hope that we can fix it soon:
