*EVERYTHING* is inherited.

The thing is that parent class initializers are not automagically
called, since their signature might be different from the child
class' __init__.

So, you have to explicitly call parent initializers from you
own derived class, but it's no biggie.

You might want to use new-style classes, by subclassing
object.  In those, you can call "super(MyClass,self).__init__(...)"
to automatically call you class' superclass, no matter what
it's name might be.
