Prague 2020-02 LEWGI Minutes

P2077R0 Associative Container Heterogeneous Erasure: Direction Review

Chair: Bryce Adelstein Lelbach

Champion: Sergey Vinogradov

Minute Taker: Ben Craig

Don't use the (old and removed) transparent key lookup API. Be consistent with P1690R1 (that's what is in the standard now).

Start Review: 2020-02-10 17:22

Implementation experience? Answer: Yes

Usage experience? Answer: Yes

Does Abseil/Folly/other libraries with heterogeneous key support have this? Answer: Yes

Do you have wording? Answer: Yes

Start Polling: 17:32

POLL: We should promise more committee time to pursuing P2077R0 (Associative Container Heterogeneous Erasure) and forward a revision rebased onto the P1690R1 wording to LEWG for C++23, knowing that our time is scarce and this will leave less time for other work.

Author Position: SF

That has unanimous consent.

End: 17:35

CONSENSUS: LEWGI sends P2077R0 (Associative Container Heterogeneous Erasure), with the guidance below, to LEWG, for C++23.

  • Rebase onto the P1690R1 wording, which is what is in C++20 (check with Chris Kennelly for details).

It's attached to the straw polls page now, so will get swept into the next mailing.
