Thanks for working on this!

I'm not sure this fixes the problem in full (see comments). That being said, I recognize that the behavior I'm suggesting below is a lot more work. I would be fine with landing this as-is because it's passing through the options and does seem like an improvement 👍

I understand why this is the way it is, but I wonder if this actually makes sense?

Feels like it should be:

var obj = {
    foo  : 1,
    'bar': 2, baz: 3, longlonglong: 4
};

or

var obj = {
    foo: 1, 'bar'       : 2,
    baz: 3, longlonglong: 4
};

@kaicataldo
Yes, I agree :) Can I work on that in different PR?.

Also fine landing as-is. Thanks for delving into this rule, @yeonjuan!
