2023-11-08 Library Evolution Kona 2023 Meeting Minutes

Chair: Robert / Billy

Champion: Daniel Towner

Minute Taker: Mark Z

Polls

POLL: Forward P2933R0 to LWG for C++26 (to be confirmed by an electronic poll).

SF	F	N	A	SA
8	13	2	0	0

Attendance: 21 (in person) + 11 (remote)
# of Authors: 2
Authors’ position: 2x SF
Outcome: Strong consensus in favor.

No issues were raised by SG1. The paper was discussed in detail, including the topic of consistency with the existing header.

Outcome

"nodiscard" is out of scope for the standard. As of LWG there's no preference on whether to add it (no requirement for consistency), slight preference to keeping it out as it may indicate on implementations wrongly.

The paper was forwarded to LWG for C++26 (to be confirmed with an electronic poll)
