It's already written. However, the general impression a month and a half
ago was that it wasn't likely to go anywhere. Since I'm not really up to
trying to make headway in the relevant groups, anyone who *does* feel like

about it. It's really a fairly obvious set of extensions (and can, in fact,
be done with only extensions).
