I don't get it. You have two classes, both with a repr implementation, and
the second one happens to be a new-style class as indicated by its being
derived from "object". Was there more to it than that?

Just in case, I copied and pasted your new-style class definition into
kirby-ghost.py and tried it out with Python 2.3 on my machine, just to see
if there was some gotcha that I had overlooked. It works just fine for me:

[david at ujae stuff]$ python -i kirby-ghost.py
>>> dir()
['Shell', '__builtins__', '__doc__', '__file__', '__name__']
>>> s = Shell()
>>> s
What famous Japanimation?
