Multiple nesting for joins.

[JakNowy]

Is your feature request related to a problem? Please describe.
I'm wonderring if it's currently possible to have multiple layers of nesting in joined objects.

Describe the solution you'd like
Ability to return multi-nested objects like

{
    'id': 1,
    'name': 'Jakub',
    'item': {
        'id': 1,
        'price': 20,
        'shop': {
            'id': 1,
            'name': 'Adidas'
        }
    }
}

Probably it's not possible without some more code, but it's indeed the next natural iteration of nested joins
