[cells-devel] defmodel

[Thomas F. Burdick]

So, when I send my local changes to cells, I included a change to
defmodel that removed :accessor, :reader, and :writer from the
generated DEFCLASS, since DEFMODEL turns around and redefines them
anyways.  Well, it turns out that that tickles a buglet in some
versions of SBCL, which causes it to emit scary-sounding warnings.  I
think it's fixed in 0.8.11, but it might be best to just forget that
change.
