Gah, you're correct...My biggest problem is I'm constructing Py classes in
Java and sometimes wanting to pass them to Python and sometimes wanting to
pass them to other Java methods that are expecting Maps or Lists.
(Actually, I wonder if the Map and Collection interfaces would compile in
Java 1.1?  They're fairly simplistic.  I don't really need the functionality
in 1.1 but I don't want to break Jython.)

Eh, I went that route for a while and found it to be a pain in the arse, in
particular, when you need to send the cookie information back to the client,
you'd have to traverse through the Jython objects, calling methods along the
way to properly format the cookie data.  (It's not just a matter of doing
"str(cookies)", since they have to be mapped into the addCookie() method.)
I also ran into some weird incompatability problems with the SmartCookie
classes, since JPython mis-identified an e-mail address cookie as a
serialized object and tried to deserialize it.
