Can't reference items removed from the store

[davidgilbertson]

If a user references an array item in the store, then empties the array, this breaks the reference.

The following fails:

it('should keep a reference', () => {
  store.testArray = [{ name: 'David' }];

  const david = store.testArray[0];

  store.testArray = [];

  expect(david.name).toBe('David');
});

When reading from the object (david.name), it's redirected to nextStore at the path store.testArray.0.name where that item no longer exists.

I'm not sure what can be done about this.

A workaround would be to use a deep clone function to 'extract' something from the store, striping the proxy away so it can be read like a normal object. That will be OK sometimes, but suck for otherwise-simple things like popping. E.g. this fails:

it('should handle popping an item', () => {
  store.testArray = [{ name: 'David' }];

  const david = store.testArray.pop();

  expect(david.name).toBe('David');
});

Perhaps in some cases (like .slice() and .pop() at least) the returned item could be stripped of its proxy.
