The biggest problem with this is that you cannot assign, pass, or return an "instance" of the array struct itself. That's because it's declared as an unnamed struct and in C two unnamed structs are not type compatible even if they have identical fields. C23 did improve struct compatibility [1] but unfortunately not for unnamed structs.
