At the request of the Tooling subgroup chair, I've attached D1873r0.0
(remove.dots.in.module.names). I'd like to discuss the Tooling relevant
parts of it on Saturday.

I would like to restrict this discussion to how tooling is intending to
make use of `.` in module names (section 2 of the paper), as the rest of
the paper is outside the scope of the Tooling subgroup and this is a very
late paper.
