Cool.
The three sorts of exceptions that the verify methods will raise are
'DoesNotImplement' (you didn't actually declare the object to
implement/provide the interface; no name is appropriate),
'BrokenImplementation', and 'BrokenMethodImplementation' (both of
which include a name, AFAICT in the code). Maybe you got a
"DoesNotImplement"? I could see how it might be confusing.
These sorts of questions should probably go to zope3-users, btw.
