I am not sure I like the deep inheritance hierarchy of FAMIX. It seems
rather brittle. Is Delphi a special case?

FAMIX was first built in VW, and we only relied on single inheritance. Since a long while we have the plan of moving towards Traits. More recently Nicolas expressed an interest in working on such a topic, and Alain Plantec extended Fame with the concept of Traits. However, until now, nothing really moved but it would definitely be great to have more energy spent there.

Cheers,
