In Python 2.2, classes and types were unified. If a class inherits
from object (or any other built-in), it is considered a "new-style"
class; otherwise, it is an old-style (or classic) class. There are
some differences in their behavior; most notably, descriptors
(computer properties) will not work with old-style classes. Old-style
classes will go away in Python 3 (I think), and all classes will have
object as a base.

Thanks Miles, I've started to go though those links, that should keep me
busy for a while !
