It's not quite clear what you mean by "linked to". Do you mean you
want to use two keys to arrive at each object? If so, the objects of
your first dictionary should themselves be dictionaries:

{ key => { key => object, key => object } , key => { key => object,
key => object } }

Or the keys could be arrays:

{ [key, key] => object, [key, key] => object }

Or perhaps you mean you want each key to yield two objects? In which
case, the objects of your dictionary should be arrays:

{ key1 => [object2, object3], key4 => [object5, object6] }
