Oh, OK. I misunderstood "should".
You're saying that if I override a function, I should be calling the
overridden function from within the override at some point.
This is an OOP design principle, but not necessarily enforced in the
compiler/IDE thingies.
It's that way because, there's not much point in writing a function that
just gets voided in the actual implementation and because it allows you
to put some shared or common functionality deeper down (higher up?) into
the foundation of the architecture.
Zat right?
