I'm sure someone can up with an example where this makes sense. However, I guess this restriction is easier and not less powerful.

Eg, Let's say class A holds fields a and b. Class C holds b and c. Then the view on things from C would be: A.a, C.b, C.c and the view from A would be: A.a, A.b, C.c.

Just moving b into a common base class is far easier to understand and implement, though.
