Certainly, I wasn't suggesting otherwise.

To be more explicit, the base exception class would
look something like

   class Exception:

     def __init__(self, message = None, **kwds):
       self.message = message
       self.__dict__.update(kwds)

     def __str__(self):
       if self.message is not None:
         return self.message
       else:
         return self.__class__.__name__
