private/package methods cannot be virtual

[Henning Pohl]

Documentation:
Member functions which are private or package are never virtual, 
and hence cannot be overridden.

I was about to write a bug report about this, because in my code 
there are tons of overridden methods which actually should be 
private/package. Can anyone tell me why this decision has been 
made? To inline them?

Do I really need to write interfaces to be able to override these 
methods?
