Variable scope within a class

Since f is a class variable, it is also an instance variable. You can
either reach it by referring to the class or by referring to the
instance. The former can be done with 'self.__class__.f', the latter by
the simpler 'self.f'. The difference is that, if self.f changes, this is
true for only 1 instance of the class, while all share the same
self.__class__.f.

Gerrit.
