I'd sort of argue that adding a __setattr__ for that purpose is
un-Pythonic (as opposed to using __setattr__ for some functional purpose
and that restriction being a side-effect). Its possible to do it, sure;
but its also possible to use __slots__ to do so as well. But its bad
form in both cases.

But, that argument is largely Nit meeting Pick and having a fight about
which kettle is blacker. :)
