6 ;;;; While most of SBCL is derived from the CMU CL system, the test

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.
