One thing I've never understood about Python 2.x's multiple inheritance 
(mostly because I almost never use it) is how you do something like this:

class Base1(object):
   def __init__(self, foo):
      self.foo = foo

class Base2(object):
   def __init__(self, bar):
      self.bar = bar

class Derived(Base1, Base2):
   def __init__(self, foo, bar):
      # now what???

I need to call __init__() in both of my base classes.  I don't see how 
super() can do that for me.  I assume I would just do:

   def __init__(self, foo, bar):
      Base1.__init__(self, foo)
      Base2.__init__(self, bar)

am I missing something here?

For what it's worth, I never bother to inherit from object unless I know 
there's something I need from new style classes.  Undoubtedly, this 
creates a disturbance in The Force, but such is life.
