Again, use of the ZODB does not help at all.

Don't get me wrong. I am addicted to programming persistent objects on
the ZODB, and I think Zope 3 with Grok offers the best way of doing

but at a very high price in terms of black magic.

But as we consider how to "sell" Grok, the fact that we have the ZODB
