And whenever you update the backend code, and **regenerate** the frontend, it would have any new *path operations* available as methods, the old ones removed, and any other change would be reflected on the generated code. 🤓

This also means that if something changed, it will be **reflected** on the client code automatically. And if you **build** the client, it will error out if you have any **mismatch** in the data used.

    Iterable<List<Integer>> partitions = Iterables.partition(list, 2);

    // Changes before the partition is retrieved are reflected
    list.set(0, 3);

    Iterator<List<Integer>> iterator = partitions.iterator();

    // Changes before the partition is retrieved are reflected
    list.set(1, 4);

    List<Integer> first = iterator.next();

    // Changes after are not
    list.set(0, 5);
