Dear Mild Shock,

Congratulations on this milestone.  I see that you've been way too
busy coding to reply to my other followups, and I hope you will for-
give me for not replying to more of your Usenet posts.

They are always delightful, and I look forward to read more of your
poetry.


Best wishes, and happy Prolog in Python!
