Thanks for that work, Barry!

I don’t disagree with any of your recommendations, and wholeheartedly agree with your constexpr changes.

While going through it I found myself really not liking the name “__cpp_familiar_template_lambda”: I find it quite opaque.  Is there is an opportunity to rename it to “__cpp_expl_lambda_template_parameters” or something like that?

Hey SG10, CWG, and LWG,

I went through the past few years of straw polls and put together a suggestion of what feature-test macros are missing: I'm proposing that about two dozen need to be added. The draft can be found here:

I included every paper on the straw polls pages, so if anybody has motivation for a macro for one of the papers I listed as "no macro necessary," please let me know. Also, if you disagree with any of my recommendations, also let me know. I already pruned an earlier list with some help, and I'd like to get this right.

I wanted to get this out earlier than the weekend before the deadline, but... that didn't happen.
