P2511R1: Beyond operator(): NTTP callables in type-erased call wrappers

2022-07-19 Library Evolution Telecon Minutes

Chair: Billy Baker

Minute Taker:

Champion: Zhihao Yuan

Chair Notes

POLL: Modify P2511R1 (NTTP callables in type-erased call wrappers) by adding a feature test macro, and then send the revised paper to LWG for C++26 classified as B2 (to be confirmed with a Library Evolution electronic poll).

Strongly Favor Weakly Favor Neutral Weakly Against Strongly Against
4 6 1 0 0

Attendance: 15

# of Authors: 1

Author Position: SF

Outcome: Consensus to forward to C++26

Summary

The feature was positively received. There was support for the author's naming choice. ABI is mentioned in the paper but the author believes that existing implementations can add this feature without breaking ABI. Some additional implementation experience would be good.

Next Steps

Modify P2511R1 (NTTP callables in type-erased call wrappers) by adding a feature test macro, and then send the revised paper to LWG for C++26 classified as B2 (to be confirmed with a Library Evolution electronic poll).

Attendance: 11 (in-person) + 6 (remote)

# of Authors: 1

Author Position: SF

Outcome: No consensus.

N: If this was either to integrate into your own callables via the invoke protocol, I'd be strongly in favor.
