There are a couple of issues here: 1. All specializations of `std::atomic` now have non-trivial default constructors. This is very much by design and not a bug. 2. Some objects...

I don't understand the issue, possibly because the example is incomplete. What's `key_comparer`? What requirement are we unable to implement? The precondition seems sufficient to guarantee that `find(broken_key{2})` will locate...

Did you have an actual problem with a program you wrote, or is this just a paper bug report? I think it's better that these constants are prvalues - they...

Check my math: `create_directory(p)` "Creates the directory `p` resolves to" per [fs.op.create.directory]/1. On my machine, Either of `create_directory("meow")` or `create_directory("meow\\")` returns `true` and leaves a directory named "meow" in my...

Which option do we prefer: * WONTFIX * `_STD _Meow(/*...*/)` [longer/hard to miss in code review] * `(_Meow)(/*...*/)`[shorter/easier to miss in code review] I don't list `::std::_Meow(/*...*/)` as an option...

> VS 2019 16.9 will support `[[no_unique_address]]`. Clang [lists this as supported](https://clang.llvm.org/cxx_status.html) in Clang 9. However, we suspect that it is not yet supported when Clang targets Windows, because MSVC...
