I believe only SBCL and CCL have ANSI-compliant CLOS implementations,
and the other compilers actually require one of the completion
libraries [e.g. c2mop] for various edge cases... for example, ECL does
not support the full method combination facility. I have no idea how
things are with ABCL although I'd be surprised to learn that they have
as good a CLOS as the two champions.
