That is normally called "repeated inheritance". :)  But as I understand
it you can't inherit from an object unless the object is a class.

Delegation normally means that a service is not implemented here but
by another class' object. There is a nice "delegation only" OO system
derived from Oberon but I can't remember its name. And I think slib
has also a OO system that uses delegation.

As far as I know Smalltalk does this.
