Can you force C++ call sites to prefix "out" for all mutate-via-reference parameters?

Out.cpp

#define out OutCatcher() <<

template <typename TYPE> struct Out
{
	explicit Out(TYPE& ref) : ref(ref) { }
	TYPE& ref;
};

struct OutCatcher
{
	template <typename TYPE> Out<TYPE> operator << (TYPE& obj)
	{
		return Out<TYPE>(obj);
	}
};

void Mutate(Out<Obj> obj)
{
	obj.ref.x = 3;
}

void Test()
{
	Obj obj;
	Mutate(obj);			// compile error
	Mutate(out obj);		// fine
}
