*grin* - its also just about impossible to do, if you try to imagine
what you would have to do to all instances when you effectively
change the __init__ method.  And some people expect it to happen
automagically...

Sorry I can't be of more help. All of the docs I have read essentially
talk about changing instances.  From a practical point of view I would 
say: "Just redefine it".  But that is not very helpful. Specially if you are
mucking about in C, as your title suggests...

It has never struck me before that the root word for
"madness" and the slang for "copulation" is the same.
I wonder if there is some sort of a message here?
