[tituswinters]

(Note: These comments are for P1355 Exposing a narrow contract for ceil2 #80.)

Discussed by LEWG in Kona:
Paper as written (noexcept + UB, novel policy / precedent)
Alisdair’s suggestion (UB, but not noexcept, Throws: Nothing)

Approve the paper as written.
SF F N A SA
0 4 6 4 1

Approve with revisions as per Alisdair’s suggestion (still UB, not noexcept, wording to include “Throws: Nothing”)
SF F N A SA
4 11 1 0 0

Revise as per Alisdair’s suggestion, forward to LWG for C++20.
Unanimous consent

Alisdair to revise this week.

These notes seem to be from a different paper (ceil2?).
