It's antithetical to the desire of keeping proxies transparent. In general, we want to discourage type checks like you just wrote. If you're getting handed an object you don't trust and need very strong guarantees on its behavior, you'll need to make a copy. This is true regardless of proxies. In your example, even if the array is genuine, there may be some pointer alias to the array that can change the array at a later time. Regards, Tom
