That's good to know, but I've noticed it was added in C++26 and seems to be supported in GCC 15 and Clang 19, but not MSVC.

I think in a few (3-4?) years it will be safe to use, but in any case not now.

Still, good to know that it exists.

I would assume that this is easy enough to implement that it will likely appear in a minor update to the upcoming Visual Studio version. MS kept updating the compiler since VS 2022, too.
