+// methods so we must define them as opaque structs identically to the way

+// NOTE: We specifically use these regardless of C++ or Objective-C++ mode so
+// the compiler will complain if we got the definitions wrong. In regular
+// C++ mode there is no way to know if we got the definitons right so
+// we depend on at least one Objective-C++ file including this header.
