Defmethod should really by written in terms of a gf like:
(defmethod intern-specializer ((s symbol))
Yes, some extensible DEFMETHOD parsing facility would be better. As I
said in my message to Scott, I think it would be better to handle that
as part of a full-fledged UI macro processing facility.
(defmethod foo (z (slot a bar)) ...) is a method specialized for
objects that have (eq (class-of (slot-value z 'a)) (find-class 'bar)).
(intern-specializer '(slot a bar)) returns an instance of class
How to refer to this class to specialize methods on it?
(defmethod ((s (eql (intern-specializer '(slot a bar))))) ...) ?
or do we have a specializer for specializers:
(defmethod ((s (specializer '(slot a bar)))) ...)
I guess I don't understand what you are trying to do here.
