The dispatch can also be done based on a particular value.  E.g.

    (cl-defmethod reactivate-mark ((marktype (eql t)))
      ;; Normal mark, nothing special to do.
      )

    (cl-defmethod reactivate-mark ((marktype (eql rectangle)))
      ;; Rectangular mark
      (rectangle-mark-mode))

    ...
