Is it time to merge the descr-branch (from which 2.2a1 was built) back into the trunk? In the fray over PEP 238 I haven't seen too much feedback on the alpha release, but there have been plenty of downloads. Telling from the bug reports, a few people have clearly been kicking the tires quite a bit.

I'm not deeply concerned from a backwards compatibility standpoint but I would like to see more documentation and more widespread understanding of the feature before we say "yes, this is the right way." I wonder how many people truly understand all of the changes. When you added metaclasses you labelled the feature experimental so you could change it once people got a sense of it. I propose you do the same thing in this case. I could even imagine using the warnings framework to tell people that they are playing with stuff that may change. As smart as you are, you are only one person, with experience with a certain set of problems. Wider understanding, experimentation and discussion might help you to improve the design...but they may break some of the features you have already added. -- Take a recipe. Leave a recipe.
