Redispatch is what A12 currently calls for, subject to pragmatic warpage. A pragma can request that no MMD redispatch happen in its scope. Or it can request that all method calls be treated as MMD from the getgo. So we need to be able to support all three of those behaviors from the caller end, not just force one behavior from the vtable. Larry
