From: Tom Honermann (tom_at_[hidden])

The updated revision, with additional changes suggested by Jens
elsewhere in this email thread, has been submitted for the next mailing
and is available at https://isocpp.org/files/papers/P2029R3.html.

If anyone has any further review comments, please let me know!

Mike, I believe this is again ready for Core review.  I know Core is
continuing to work through Davis' lookup paper, please let me know when
you can fit it in.

Tom.
