Congratulations to Ted Leung (and to Frank Wierzbicki):
The Sun is going to shine on Python.
Their work at Sun will extend well beyond Jython, but Ted's post reminded me of my recent experiences. Jython 2.2 sure made it pleasant and easy to get what I needed out of CDK, and to integrate the results into a CPython app via pickle and subprocess.
I did miss some language features such as yield which have appeared in CPython since 2.2. Maybe at some point Ted and/or Frank will have time to re-sync Jython with CPython?
 I had one intermittent problem with this approach. See the next post.
