I agree.  I see some nicer (IMHO) alternatives...  Apart from the 
recipe I mentioned
in the recent post (although I am *not* convinced it should be added to 
the stdlib)
some decorator-based way may be nice, e.g.:

     @namedtuple(fields='length weight is_poisonous')
     class Snake:
         def hiss(self):
             return 'hiss' + self.length * 's'

Cheers.
