Nice experiment.

There are two possible forwarding handlers: 1) one that uses the "virtual" prototype passed to Proxy.create 2) one that uses Object.getPrototypeOf(target) Option #2 is what's in the proposal [1]. I think that's a safe bet, since most proxies will not want to interfere with the prototype chain and will probably even set the virtual prototype equal to the target's prototype, in which case #1 and #2 are the same. We could make the choice between #1 and #2 configurable, but I don't think it's worth the additional complexity.
