It’s worth pointing out that C also warns (and C23 straight-up *errors*) if you replace `nolock` w/ `noreturn` iirc, so either that’s also a bug or that’s intended; I think I was going to ask Aaron about this as he’s the C expert, but I forgot about that too, again because of the `AttributedType` stuff.
