We could instead say that all objects have a [[DefaultHandler]] which contains the default trap implementations. Then object's that have a [[Handler]] are "proxy objects". For trap resolution if an object has a [[Handler]] and the [[Handler]] has the given trap, invoke it. If an object does not have a [[Handler]] or [[Handler]] does not have the given trap, then, for derived traps invoke the object's [[DefaultHandler]]'s trap, for fundamental traps perform the abstract spec defined pseudocode for the given internal method. Then proxy fixing would mean that the object will no longer have a [[Handler]], and "Proxy.createFrom" means that the object will now have a [[Handler]]. We could also define default handler's for object types which override certain internal methods such as Arrays and Functions. These would inherit the trap implementations from Object's default handler.
