If you are willing to require that the args be passed as a tuple (extra 
pair of parens) I believe you could do

    def __init__(s, args):
        s.x, s.y, s.z = args

This even checks for correct number of actual args.  I believe part of your 
underlying point is that you do not (usually) in this type of situation 
really need or want the args to be separately named locals since you just 
want to attach them to the instance.

(Way too late, may have made an error.)
