scope. If you have added your own Proxy object, then you could have a problem. Another potential risk is around
the "private", underscore preceded methods and properties. I had to reserve those in addition to the standard ones,
so you won't be able to use keys that overlap with those underscore preceded properties and methods in a harmony-proxies
environment.
