sure, we don't do it (like many "object" implementations don't do it -- java for example). Thats one right way to do it.

Oracle9i supports single inheritance directly. I guess you could say we do it right.

you would have to define "correctly".

We support substitutablity, the ability for a supertype container to hold a subtype instance.
