For reference_wrapper to be Assignable, it has to hold a pointer to the object
it references (if it holds a reference, like reference_to_value does, it
wouldn't be Assignable).

The probably is getting that pointer type. If T is not a reference, it's just
T*. If T is a reference, we need
  typename remove_reference<T>::type*

... and remove_reference doesn't work on all compilers. Maybe there's another
way to get a pointer type T* from a reference type T&?
