This folder contains an example that shows how to implement a reflective class-based system. There are three main classes:

[111, 98, 106, 101, 99, 116]

root of the inheritance graph

[99, 108, 97, 115, 115]

default metaclass for all instantiable classes

[97, 98, 115, 116, 114, 97, 99, 116, 95, 99, 108, 97, 115, 115]

default metaclass for all abstract classes

Each class inherit all the methods form the other two classes and from itself (without any inheritance loops of course ;-).

You can find more sophisticated versions of these classes in the roots example. If you are not familiar with the concept of metaclass used in this example, see the metaclasses example first.
