* When you're accessing members in an array or an object, you're
* doing this via an internal member object. This is an object that
* keeps track of the array to which it belongs, and that will update
* the array when the member is modified
*
* You are not supposed to instantiate this class. An instance of it is
* created when you call Value::operator[]
