When a base class has an abstract method with an implementation, derived
classes are still supposed to be required to override those methods according
to the spec:

Abstract Attribute

... snip ...

Functions declared as abstract can still have function bodies. This is so that
even though they must be overridden, they can still provide 'base class
functionality.'
