By "dispatching" do you mean runtime polymorphisim as opposed to compile-time polymorphisim? In other words, you wouldn't be allowed to call a primitive routine with a classwide type, but you'd still be allowed to call an inherited routine (or an overrided version of one) with a specific tagged type object (not using 'class). -- T.E.D.
