[Zope] objects as values in a python dictionary

[Peter Bengtsson]

This concerns both Python Script and External Methods. I haven't tried it
with DTML (if possible).

A dictionary can use objects as values I think.
res={}
res[string] = "A wicked module I use often"
res[context] = "This is where you were :)"
That works, but it doesn't work when I loop over objectValues

for object in folderobject.objectValues():
    res[object] = "yeah"

The error message is AttributeError and __hash__ something.
What have I missed?
