On page 2-72 of 88-002, the following remark appears: `` The function SLOT-BOUNDP is implemented using SLOT-BOUNDP-USING-CLASS.'' Since SLOT-BOUNDP-USING-CLASS is not described in the document, the usefulness of this remark is lost on me. The same goes for the similar remarks for the functions SLOT-MAKUNBOUND and SLOT-VALUE.
