I'd like to sprint on it before PyCon; we'll have to see what my
schedule allows.

I think the branch is in an awkward state, because of the new features
added to Python 2.4 after the AST branch work ceased.  The ast branch
doesn't handle generator expressions or decorators; extending the ast
to support them would be a good first step.

There are also the simple logistical questions of integrating changes.
 Since most of the AST branch changes are confined to a few files, I
suspect the best thing to do is to merge all the changes from the head
except for compile.c.  I haven't done a major CVS branch integrate in
at least nine months; if someone feels more comfortable with that, it
would also be a good step.

Perhaps interested parties should take up the discussion on the
compiler-sig.  I think we can recover the state of last May's effort
pretty quickly, and I can help outline the remaining work even if I
can't help much.  (Although I hope I can help, too.)
