re: In Symbolics' implementation notinline SLOT-VALUE
does not call SLOT-VALUE-USING-CLASS for the standard metaclass.
I thought it was supposed to, so that the user could hang hooks.
Or, are you simly referring to an optimization of the notinline
case when there are no user-defined methods?
From p.13 of the July 30, 1990 metaobject protocol specification draft:
"Any method, defined by a portable program on a specified generic
function, must have at least one specializer which is not a specified
So "the standard metaclass" implies "no user-defined methods".
