Given you aren't sure since SG1 this might be useless but... do you have a paper number? Or, more likely, know an author's name ?

- legobmw99 8mo agoSeems like its p3125r0
- tialaramex 8mo agoThanks! https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2025/p3125r4.html https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2025/p31... (is the current version of that paper, the tracking ticket insisted there's a P3125R5 and that LEWG had seen it in 2025, but it isn't listed in a mailing so it might be a mirage) You know it's a Hana paper because it wants this to be allowed at compile time (C++ constrexpr) but joking aside this seems like a nice approach for C++ which stays agnostic about future implementation details.
- trws 8mo agoIt’s Hana Dusikova’s paper IIRC.
