 Its not permitted. Not directly. But you can define

 template<class T> T* operator&(const T &x) {
  return const_cast<T*>(&x)
 }

 *&1 = 2; // legal (but useless)

I dont recomment this -- which is why I argued that the built-in
address of operator should take the address of temporaries.
(And do it correctly -- preserve constness, which the above
template doesnt)
