Walter volunteers to check that this is done.

EWG February 2021 polls:

Poll: Forward P2013R3 "Freestanding Language: Optional ::operator new" to Core.

SF	F	N	A	SA
8	15	3	0	1

Poll outcome: ✅ consensus.

Salient comments:

• (Strongly against) The freestanding implementation parts of the standard impact a very small number of users and the committee spends a disproportionally large amount of time with it. I’m against any time spent on freestanding language work with the exception of its removal.
• Making freestanding more useful is a good thing.
• Consistent with C++ core principles to move errors to build time whenever possible.
• Matches existing practice.
• This is an important topic.

P2013R4 Freestanding Language: Optional ::operator new (Ben Craig)

[AaronBallman]

Removing the SG22 tag after discussion with the proposal author -- there is not enough compatibility concerns with C for this to be worthwhile for the study group to look at.

The state of the paper after CWG review is that it touches only LWG wording. Forwarding ownership to LWG.
