What is the likelihood that __nonzero__ could be renamed (at some point in
the future) to something a bit more intuitive, like __bool__? I know there
would be a lot of user code to change, but assuming one day the hammer will
drop and everyone's __nonzero__ will have to change to return a bool, I
wouldn't mind seeing the method renamed as well.  Or is this a lost cause at
this point?
