Something has changed in the way Zope 2.3 handles the __getitem__ protocol.
This breaks SkinScript's use of OLD.
The fix is to patch Agents.py so that the class _memento explicitly
provides a __getitem__ method.
ZPatterns may need similar fixes elsewhere. See my message to zope-dev
earlier this week about the difference in using __getitem__ on Dataskins
from a Specialist and in the ZODB.
