(a) The feature is *not* currently in C2y, so a patch proposing it is proposing an extension, which -std=c2y -pedantic should diagnose. (b) There should be tests that -std=c23 -pedantic gives a warning for this, -std=c23 -pedantic-errors gives an error; and similarly for -std=c2y, unless and until the feature gets into C2y. -- Joseph S.
