Doesn't seem to detect reference updates (equal, but not identical)

[nevir]

reducer(state = {}, action) {
  // I would expect this to trigger an error, but it doesn't
  state.foo = {};
  return state;
}

One I give it differing values, it does:

let count = 0;
reducer(state = {}, action) {
  // boom
  state.foo = {count: count++};
  return state;
}

Nice catch, will try to fix it soon

Awesome :)

@nevir I've pushed some changes to the logic to detect mutations, and this should be fixed. I'll release a new version soon but if you want/need this now you can test with current master. Feel free to reopen if this is still not working!
