I wrote that recipe back before Python 3.x supported super() without parameters,
and near equivalent functionality was part of the new super PEP as an option.
However, Guido decided to go with the much simpler super().attr with no shortcutting.

If you think the pure-python version of the recipe is complicated, you should have
a look at the performance-optimised Pyrex version ;)
