If multiple inheritance is deemed complex, adaptation is even more so: With multiple inheritance, you can quite easily see from the source code how things are put together. Adaptation follows the "inversion of control" principle. With this principle, how a function is implemented, is decided outside and can very easily be changed (e.g. through configuration). This gives great flexibility but also nightmares when things do not work as expected... -- http://mail.python.org/mailman/listinfo/python-list
