Are you sure you haven't reversed the options? My option 1 calls only
the derived class' __init__ and leaves it up to that method to call
the base class' __init__. My option 2 calls all base* class __init__
methods (buttom up) with the same argument list. This sounds like the
reverse of what you're describing...
