This is very cool. If it can reliably work even for the examples provided, one can wrap a lot of C++ methods comfortably and reduce a ton of friction.

Is the 2026 spec still at the draft stage?

Update: Nevermind - just read that it only works with Bloomberg’s clang fork. Hopefully it’ll land in upstream clang soon.

It is making it's way to GCC as well: https://www.reddit.com/r/cpp/comments/1ojbv1a/gcc_implementa...

It is officially part of C++26, so only a matter of time before being part of the major compilers (:

I've added a pre-built image in the github repo, feel free to try it out if you are curious and let me know if you face any issues/bugs!

Thanks again for creating this and sharing it here. Honestly makes me want to pick up C++ for a project just to try it out (along with reflection and other new features).

But why isn't it in Rust? I thought all new code had to be written in Rust?

Bruh...reflection. No can do in Rust.
