Discussions about proxy-polyfill

Just revisited: https://github.com/GoogleChrome/proxy-polyfill and reduxjs/react-redux#1179 Two caveats:

1. It doesn't support has and ownKeys handler.
2. It doesn't detect accessing new properties. In other words, it would work only if state is only accessed by get with existing properties.

Suppose state = { counter1: 0 }, with proxy-polyfill:

1. 'counter1' in state can't be trapped.
2. state.counter2 can't be trapped.

As in dai-shi/react-tracked#6, we need somebody to try out reactive-react-redux with polyfill.
