If you use vars(self).update(locals()), it even looks halfway pleasant ;)  I'm not sure what python-dev's current opinion of vars(obj) is though (I'm hoping someone'll tell me).

Of course, both of these fall over for __slots__'ful classes.  It'd be nice if there were a general way to deal with attributes of an instance, regardless of the implementation details of its memory layout.
