Oh, I see. No, the Explorer doesn't have these because locatives don't have
a DEFCLASS slot option comparable to :READER and :WRITER; an explicit
DEFMETHOD using (LOCF (SLOT-VALUE ...)) would be required. Since few people
use locatives, I don't think it would be worthwhile for :ACCESSOR to imply
automatically creating a LOCF method as well as a SETF method.
