A wrapper object will contain one reference and compare by x==y <==> x.ref is y.ref. It's also worth noting that Python objects have a hash function as well. This function is necessary to put an object into a set or dictionary. It is supposed to sometimes collide for different objects, though good implementations of hash try to make it less likely.
