The author of Neon went on to make Actor, an Object Oriented environment
for MS-Windows. Is Kriya Systems still supporting Neon? There were
many bugs reported in the early versions, which turned me away. I'm
interested in this if the support has been decent.

It might also be interesting for you to share some of the OO implementations
that you find useful, or cumbersome, via example. I'm sure many others
would be interested.
