Well, sure, since you have defined it. Perhaps that definition was fine
when we only had CLASS(*). I am proposing that it ought to be changed
now to *only* include CLASS(*), and TYPE(*) be separate. Polymorphic
should mean an object that can have different dynamic types.
Assumed-type objects should be classified as having no type. It is
different from "has a type that I do not know at compile time". I know
it requires more work to invent this new kind of untyped objected, but I
think it is important,
