In article:
http://www.linuxjournal.com/article.php?sid=4540
Chuck Esterbrook mentions an elegant technique
called 'Mixin'.

Assigning to __bases__ is useful if you want to add
ancestors without changing the object's source code.

It does not work with new-style classes because the
 .__bases__ attribute is now read-only.
This is also mentioned on
http://www.python.org/2.2.1/bugs.html
at the bottom but I could not find a bug-report here at
SF.
