The issue of efficiency may not be a problem with Python 2.2
or later since it provides new mechanisms that avoid the need
to use __setattr__ to solve this problem. (e.g. __slots__,
property, __get__, and __set__). So it becomes more
of an issue of which style people prefer rather than simplicity
and speed of the code.
