Since Python 2.6 is out, I would recommend using a class decorator for
this task.
The class decorator is not inherited, so in order to decorate methods
in subclasses
one has to repeat it, which I see as a feature (explicit is better
than implicit).
Otherwise the readers of your classes will not have any visual clue
that something
magic is going on; moreover, you will lower the risk of decorating
methods
that should not be decorated (I mean, in case of accidents).
