Good point about being subclass friendly...  I wonder if there's an easy 
way of doing what update does though...  Update (and therefore __init__) 
allows you to pass in a Bunch, dict, (key, value) sequence or keyword 
arguments by taking advantage of dict's update method.  Is there a clean 
way of supporting all these variants using setattr?
