I think I am misunderstanding something basic about python/zope
here. Why does a TOC object evaluate to false?
I think the basic misunderstanding is about what happens if you say...
if FOO: ...
Python will try to evaluate using steps such as looking for methods
like __nonzero__, __len__, etc, and you're not aware what these may
evaluate to given your object. A Folder, for example, evaluates to
False when it is empty.
You should use a different test to determine if that item exists.
