Cannot do `deep.nested` on an array, have to wrap it with an object

This was a stackoverflow question - https://stackoverflow.com/q/53906051/1828637

He has a const payload = [{ id: 0 },{ id: 1 }] and wants to do the following:

expect(payload).to.nested.include({
  '[0].id': 0,
  '[1].id': 1
});

But it does not work. He has to wrap it to get this to work:

const wrappedPayload = { a: payload };
expect(wrappedPayload).to.nested.include({
  'a[0].id': 0,
  'a[1].id': 1
});

I think this is a bug.

In terms of current functionality, I don’t think there’s a silver bullet. Some options:

// Option 1
const wrappedPayload = { a: payload };
expect(wrappedPayload).to.nested.include({
  'a[0].id': 0,
  'a[2].value': 'qux'
});

// Option 2
expect(payload).to.have.nested.property('[0].id', 0);
expect(payload).to.have.nested.property('[2].value', 'qux');

// Option 3
expect(payload).to.include.deep.ordered.members([
  { id: 0, value: 'foo' },
  { id: 1, value: 'bar' },
  { id: 2, value: 'qux' }
]);

In terms of possible changes to functionality to support this:

1. Update the .include assertion to support .nested with array targets
2. Update the .members assertion to support .nested

Thanks very very much for sharing this info @meeber !
