Asking *where* the value is is a completely different question to asking 
*what* the value is.

I demonstrated that earlier in this thread, where I implemented the 
beginnings of an int-class using unary notation, using a linked list. The 
value of the object was encoded by the length of the chain of objects, so 
there was no "where" that value was stored. It was distributed over the 
entire linked list.
