The case when they are not the same is when the proxy is in the
prototype chain (regardless of what kind of object is "underneath").
See the third example at:
The proxy object is on the prototype chain and in the "get" trap, "rcvr"
is the "base object" while the third optional proxy argument is the
proxy prototype object.
