I'm tired and I have flu, maybe that make me feel so confusing about that.

So, I can't have a method in the subclass with the same name but
different signature or return value, of that method in the superclass
(because in fact that is what Gambas will prevent).

If I do that Gambas will raise an error.

Right?
