    There is no way to store an empty object/array/null value.
    There are also no actual arrays.  Array values get stored as objects with integer keys.
        (If all keys are integers, it will be returned as an array.)

    Basically, it's one giant tree of hashes with string keys.
    Simply write a value to any location, and the intermediary locations will automatically come into existance.
