187	nit: we can claim this done as we implemented `decay-copy` as a macro to `static_cast` which doesn't have the problem the issue mentioned

187	Thanks! Do you know in which version of libc++ this was fixed?

There are many interesting papers. LGTM % comment.

79	Why is this in here? AFAICT it only has core wording changes.

187	It is this commit https://github.com/llvm/llvm-project/commit/cb8a0b07974eb6a6aa681c30ce694e13b33a3db5 (I don't know how to find out which version though)

187	You can just search for the title. If you only find one commit, look at which branches it is part of (in this case, LLVM14). If there are multiple matches just check which one was cherry-picked onto a release branch and that's the correct version.

Thanks for the reviews!

187	Thanks!

79	Good catch I thought I had removed that, but instead removed P1223R5 ranges::find_last(), ranges::find_last_if(), and ranges::find_last_if_not(). So I'll rectify that before landing.
