							 However, if
   the forthcoming MOP spec includes this requirement, I'd like to
   include it as a possibility in the FAQ answer.

The MOP spec does not require SLOT-VALUE to work on structures.  This
requirement was dropped in the final version because some people were
concerned that it interfered with efficient structure implementations.

The terminology in the MOP spec makes it a simple matter for an
implementation to document that SLOT-VALUE does work on structures---it
need only document the existence of methods on SLOT-VALUE-USING-CLASS
et. al.
