Hello, Graham.  I often found it useful, in a hierarchy of classes, being
able to preset a default value in all objects by using a class variable in
a base class, then overriding this default at __init__ time (or otherwise)
in only a few of the derived classes.  This relies on the fact that `self',
everywhere, finds class variables when not overridden.
