Chair: Fabio Fracassi

POLL: Advance P2300R5 to electronic polling to send it to LWG for C++26

SF	F	N	A	SA
15	6	1	0	0

Authors: 4

Participants: 32

Outcome: Strong consensus in favor

Summary

We discussed questions regarding P2300 that should be answered before C++26 ships. We send P2300 to electronic polling now (for C++26) to establish a status quo against which to diff proposals that want changes or additions.

The broad question/checklist is:

• P2547: Language Support For Customisable Functions (needs Evolution review).
• P2079: Execution Context (needs Concurrency review).
• P2300-based networking.

We had an introduction to P2547: Language Support For Customisable Functions at the end of the session

Outcome

We send P2300 to electronic polling now (for C++26) to establish a status quo against which to diff proposals that want changes or additions.

@jfbastien Library Evolution request that Evolution evaluate this paper as soon as is feasible; we believe it is important to our plans for senders and receivers and the design of Standard Library customization points.
