Linker errors with Interfaces

[Andrej Mitrovic]

Reading from TPDL again, the "final void thereandback()" method in the
interface is what the user code is expected to call. That method calls two
private methods. But it will call the two private methods in the interface,
not the two from the derived class (since private methods are not virtual).
E.g. calling thereandback() explicitly from a derived object will call the
interface method, since it is final, which then calls the private methods
from the interface.

It's like a dead-end here.
