Doc mismatch with Javascript object

[beenotung]

hz version: 2.0.0

In the [doc] (http://horizon.io/docs/users/), there is a code snippet:

horizon.users.find("D6B8E9D0-CD96-4C01-BFD6-2AF43141F2A7").fetch().subscribe(
    (user) => {
        // add a 'name' key
        user.data.name = "Bob";
        horizon.users.replace(user);
    }
);

However, the shortcut horizon.users does not exist.
Also, the fetched object doesn't have data field.
