+1. This also matches with the behavior of JSON.stringify(aProxy):
serializing a proxy as data should simply query the object's own properties
by calling the appropriate traps (in the case of JSON, this includes
intercepting the call to 'toJSON').
(Every algorithm that mentions proxies, or really any other object
