Yup, but that won't catch the case where the thing being cut and pasted
doesn't exist where it says it does in the __cp data. Also won't help with
silly things like trying to rename an object to a name already in use. And
all the other wierd and wonderful situations the CopySupport handles
already.

It's a shame CopySupport's exception raising is so interesting. If it raised
class-based exceptions (idea: could MessageDialog actually be implemented as
a class-based exception? hmmm....) and those classes were exposed to
PythonScripts (are there more exceptions available in RestrictedPython in
Zope 2.4?), this could all be handles a lot mroe cleanly and nicely.

Thanks, I've mailed it to Shane and asked him to pass it on :-)

cheers,
