Maybe I was using sloppy terminology, but as far as I can see, `cl-defstruct'
can not have a parent relationship, so what I call inheritance-based
dispatch isn't really possible with cl-defstruct?

(defclass foo () ())
(cl-defmethod val ((foo foo)) 0)
(defclass bar (foo) ())
(cl-defmethod val ((bar bar)) 1)
