Good; hopefully we can get somewhere then.

Ah, of course. I'd forgotten how cool Jython was in some ways.

Well, I don't want to make more work for you - I imagine Guido's doing

Can you point me to the code in CVS that implements this sort of
thing? I don't really know Java but I can probably muddle through to
some extent. We might as well have CPython copy Jython for once...
