Zope has many other problems under 0.5.x - don't even bother. The 0.6 effort 
(CVS main branch) is attempting to fix those problems.

In this particular case, Zope has a rule that you can't publish an object if it 
starts with an underscore. I simply didn't take this into account when I added 
the _file thing. I will look into adding a different prefix for Zope compatibility. 
Possibly @file@ or @@file or similar.
