The outer class is referenced via the property outer. However, if the inner 
class is static, then it has no such property and is not tied to a specific 
instance of the outer class. In such a case, it can access the private members 
of an instance of the outer class, but it's not tied to an particular instance. 
Non-static inner classes (like yours above), however, _are_ tied to a particular 
instance of the outer class, and they have the outer property which is the this 
of the outer class.
