This is the first time I've seen the init as update idiom - this is clearly
not a case of love at first sight. Objects cumulating data over subsequent
calls of __init__() seems unintuitive to me.
Why isn't dict.update() enhanced to handle all three cases? You might
actually use the same implementation for both __init__() and update().
