Mailing review 26-07-2021-13-09-2001

Lots of interest for this paper to land in 23 along the already approved stacktrace proposal.
A R1 was provided during the review addressing most of the concerns and feedback offered during the review.
A core expert offered some wording review

We probably still want to hear from implementers directly about the potential issues pertaining to ABI stability.

Given all the feedbacks were addressed and reviewers are happy with the general design and wording,
I recommend that this paper is reviewed during a LEWG telecon.

Deferring to C++26 due to lack of time.

@brycelelbach : Can you elaborate a little more about this? While the "infrastructure" is very nice, the killer feature for many is for existing code, and the standard library especially, to throw exceptions with stack traces.

@brycelelbach : "Lack of time" means lack of time. It means the committee doesn't have the bandwidth to work through the issues of the proposal (while still doing what's already on their plate) before C++23 needs to be feature complete.

@NicolBolas : I think you meant to address me. Anyway, there seem to be issues with the proposal. I was hoping for a few words about what issues have come up.
