I have no idea what this is. Maybe you are thinking of noreturn? Even
so, _Noreturn (what noreturn is defined as) is a function-specifier,
not a type-qualifier, and is not allowed in the brackets of an array
declarator in any C standard.

Just FYI, all of the above (except noret, which is nonsense) are valid
in C99. I don't think any of this changed in C23.
