P1648R1 std::extended: Direction Review

Champion: Mingxin Wang

Minute Taker: Bernhard Manfred Gruber

Start Overview: 07-17 10:56

Start Review: 11:09

If we like this, we should explore deploying this in the standard library.

Do we need the make_* function, can't we just use CTAD? Sounds like we need make_extending_construction because we need the T to be explicit and there is no partial CTAD.

Bikeshed all the extend naming.

Start Polling: 11:17

POLL: We should promise more committee time to pursuing D1648R1, knowing that our time is scarce and this will leave less time for other work.
