Java code often uses protected abstract methods for functionality that
is to be provided by a subclass, but is not part of the external
interface. That seems like a pretty legitimate use (and the only one
I've noticed) but as usual it's only because Java is so braindead. In
Lua (or C++), I'd make the missing function a class parameter.
