Hi Marcel!

I will post a phabricator review for the patch (2 actually, since there's an llvm and a clang change) shortly. Not for immediate inclusion, but to allow anybody  to use it in their own codebase if they want, while perhaps starting a discussion for possible upstreaming. The feature hasn't been universally supported in the past.
