I think that's exaggerating consensus. The vote in Graz was between
Martin's and Chris's approaches as a whole rather than specific details
(the particular thing I had in mind as a key thing to prefer about Chris's
approach then was that it avoids allowing forward declarations of
non-parameters, rather than other things about where semicolons are used).

Diagnostics don't start with an uppercase letter (except when one is
appropriate in the middle of a sentence), and don't use braces around a
single statement like this.
