Jason Merrill <jason at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jason at gcc dot gnu.org --- Comment #3 from Jason Merrill <jason at gcc dot gnu.org> --- MSVC also doesn't implement the stated C++23 behavior, though EDG does. Given how widely unsupported this has been, I probably wouldn't bother implementing it at this point, and just treat this as a pack expansion like Clang.
