I have no problems with revisiting all the uses of the term ``undefined''
and changing some or all of them. Moon's instance 2, though, mistakenly
uses the term ``undefined'' when it should say ``unspecified.'' I have
already fixed it (several days ago) in the files:
2. The order of evaluation of default value forms and the order of
evaluation of {\bf :initform} forms are unspecified.
