Your “top five” ISO C++ feature proposals

The ISO C++ committee now regularly receives many more proposals than we can/should accept. For the meeting that begins this coming Monday, we have about 300 active technical papers, most targeting post-C++20. I now regularly get asked, including again a few hours ago, “how do we know which of these customers actually want and will use? what is our data that we’ve prioritized them correctly?”

So a colleague has challenged me: Can the ISO C++ committee get useful information by crowdsourcing public feedback on ISO C++ proposals? I don’t know, so let me try by asking one targeted question…

Survey: If you could pick  at most five of [list of active papers]  to be eventually adopted in the C++ standard in some form, which would you pick and why (ideally, how you would use them in production)?

I don’t expect you to know all of the proposals (and I know it’s a big list!), but I suspect many of you know about  some of them that matter to you. I will share your feedback with the ISO C++ committee and post the results publicly. Thanks again for all of you who’ve already provided feedback in our spring C++ developer survey, that feedback is being used by the committee and the experiment here is try for finer-grained feedback at the proposal level. If this works perhaps we can explore things like allowing community comment/upvote on these issues.

Thank you in advance for your time, it’s appreciated and helpful.

Note: PLEASE use the survey (not the comments section on this post) to respond to this question, because the survey form makes it easier to track and use the data.

Please do use the comments section below for other discussion, including suggestions about other ways the committee might usefully engage the community.
