Deserialize ``s`` (a ``str`` or ``unicode`` instance containing a JSON
    document) to a Python object.

    *encoding* determines the encoding used to interpret any
    :class:`str` objects decoded by this instance (``'utf-8'`` by
    default).  It has no effect when decoding :class:`unicode` objects.

    Note that currently only encodings that are a superset of ASCII work,
    strings of other encodings should be passed in as :class:`unicode`.

    *object_hook*, if specified, will be called with the result of every
    JSON object decoded and its return value will be used in place of the
    given :class:`dict`.  This can be used to provide custom
    deserializations (e.g. to support JSON-RPC class hinting).

    *object_pairs_hook* is an optional function that will be called with
    the result of any object literal decode with an ordered list of pairs.
    The return value of *object_pairs_hook* will be used instead of the
    :class:`dict`.  This feature can be used to implement custom decoders
    that rely on the order that the key and value pairs are decoded (for
    example, :func:`collections.OrderedDict` will remember the order of
    insertion). If *object_hook* is also defined, the *object_pairs_hook*
    takes priority.

    *parse_float*, if specified, will be called with the string of every
    JSON float to be decoded.  By default, this is equivalent to
    ``float(num_str)``. This can be used to use another datatype or parser
    for JSON floats (e.g. :class:`decimal.Decimal`).

    *parse_int*, if specified, will be called with the string of every
    JSON int to be decoded.  By default, this is equivalent to
    ``int(num_str)``.  This can be used to use another datatype or parser
    for JSON integers (e.g. :class:`float`).

    *parse_constant*, if specified, will be called with one of the
    following strings: ``'-Infinity'``, ``'Infinity'``, ``'NaN'``.  This
    can be used to raise an exception if invalid JSON numbers are
    encountered.

    If *use_decimal* is true (default: ``False``) then it implies
    parse_float=decimal.Decimal for parity with ``dump``.

    To use a custom ``JSONDecoder`` subclass, specify it with the ``cls``
    kwarg. NOTE: You should use *object_hook* or *object_pairs_hook* instead
    of subclassing whenever possible.
