Actually, boxes with integers in them isn't the appropriate analogy.
Consider the naming of cats. My cat is known to me as Paddy. My next
door neighbor sometimes feeds her and is known to her as Stripes. The
cat also is known as kitty to my youngest daughter. The cat has no idea
what its name is, it just is and eats. So three labels, one object.
Putting the object in three boxes isn't right -- how could you know
(other than checking the id()) that they're the same?
