Concrete classes -- stylistic question

[Matt Gerrans]

The class in the cookbook is called "Bunch," but it is the same
implementation.

The Python Cookbook is most excellent for questions such as this one and is
a joy to browse for clever, efficient and simple ways of doing many things.

As Gerhard Häring mentioned earlier in this thread, the recipes are online
at http://aspn.activestate.com/ASPN/Python/Cookbook/;  I just got the Python
Cookbook in paper form and, to echo the sentiments of a recent post more
succinctly, if not more eloquently, it is a great addition to a Python
programmer's library.    It is great as a reference and also fun to just
browse around learn good Python programming techniques and habits.
