No, I meant what I said. N1761 addresses solely the cases where the arguments are arrays of intrinsic element types, or pointers to intrinsic types. It may be intended to address more, but I do not think that it does. And my proposal doesn't handle derived types properly, either, but that can be solved in the same way that IBM PL/I on the System/370 did. Anyway, that will probably have to wait until late January.
