Champion: Lewis Baker
Chair: Fabio/Ben
Minute Taker: Khalil Estell

Summary

POLL: Move the facilities of P3325R0 to std:: namespace (make it a more general "lookup" facility)

Attendance: 14 IP + 4 R
Author's Position: N/A
Outcome: consensus against

POLL: Approval poll of the names:

• [status quo] env/prop: 8
• environment/property: 6
• env/property: 10

POLL: In P3325R0 Change name prop to property, leave env as is.

Attendance: 12 IP + 4 R
Author's Position: N/A
Outcome: No consensus for a change

POLL: P3325 needs to support initialization from a parenthesized expression (even if that makes the facility a non aggregate)

Attendance: 12 IP + 5 R
Author's Position: N/A
Outcome: Consensus against

POLL: Forward P3325R0 to LWG for C++26 (to be confirmed by electronic polling)

Attendance: 13 IP + 5 R
Author's Position: N/A
Outcome: Consensus in favor

A: I'm not against the facility, just against forwarding to LWG without more context
SA: Too fast too early. This feels rushed and I have experience and regrets with doing this in the past.

Next Steps

The paper was forwarded to LWG for C++26 (as B3 - addition) (to be confirmed by a Library evolution electronic poll).

P3325R1: A Utility for Creating Execution Environments

2024-07-16 Library Evolution Telecon Minutes

Champion: Eric Niebler
Chair: Ben Craig
Minute Taker: Guy Davidson & Mark Hoemmen

Summary

We did a wording review.
Few fixes which came up during the review:

• Adjust target of the change from P2300 to working draft.
• Add new paragraph to mandate that prop type's query be well formed. If you pass an int for an allocator query, that should fail during prop construction. Need to do that while keeping prop as an aggregate.
• Remove [[nodiscard]]
• Remove Args... argument packs from query

Next Steps

The author should apply the requested changes, the next revision of the paper (P3325R2) will be seen by LEWG in an upcoming telecon.
