Object methods are missing IntelliSense

Hey,

methods in POJOs don't autocomplete like here:

``` javascript
var foo = {
    bar() {
    }

    baz() {
        this.bar<ctrl+space>
    }
}
```

although it works just fine for ES6 classes:

``` javascript
class Foo  {
    bar() {
    }

    baz() {
        this.bar<ctrl+space>
    }
}
```
