You are right, it would be possible to just allow the printf format string type for all constant strings, either C strings or ObjC strings or C(++)11 char{16,32}_t literals, or even wchar_t. Or C++11 custom string literals. That would make __NSString__ and __OFString__ unnecessary and just allow format(printf, …) for all of them. I think this is a cleaner solution and the way to go!
