Hey,
I thought that an abstract inner class would be one that a subclass (of
the outer class) must implement, not one that must be extended. Similar
to abstract methods.
But have you considered enums, traits and interfaces? I assume inner
classes would work as expected if defined on traits or enums, but what
is going to happen if I try to define one on an interface?
