Honest to say, there is no solid connection between Dao and Python.
It's just that I had received some good suggestions and comments from
these groups when I made a few previous announcements in these groups.
So I guessed somebody might be interested in Dao, and thought it might

3 and 2.6 are compatible. so develop on 3, to make sure you don't use old
junk, and then switch to 2.6 if you need to. there are a few wrinkles in

True # all good so far
>>> c is d
