I don't think it is really accurate to say that an old-style class 
"starts from nothing". It doesn't have an explicit base class but it 
does have all the old-style class machinery which is built in to Python.

I don't know why new-style classes are smaller though. My guess is that 
it is because there was an opportunity to streamline the class structure 
based on experience.
