PyArg_PTAK was originally used, but really isn't well suited to what we're
trying to do, and ends up raising obscure errors of it's own (or, more to
the point, goes subtly wrong without warning the user).

Giving the C DialectType a setattr which does the input validation is
probably the better answer.
