on attempt to decode an invalid string. If strict is False then literal
control characters are allowed in the string.

r a Simple JSON decoder
Performs the following translations in decoding by default:
+---------------+-------------------+
| JSON | Python |
+===============+===================+
| object | dict |
+---------------+-------------------+
| array | list |
+---------------+-------------------+
| string | str |
+---------------+-------------------+
| number (int) | int |
+---------------+-------------------+
| number (real) | float |
+---------------+-------------------+
| true | True |
+---------------+-------------------+
| false | False |
+---------------+-------------------+
| null | None |
+---------------+-------------------+
It also understands ``NaN``, ``Infinity``, and ``-Infinity`` as
their corresponding ``float`` values, which is outside the JSON spec.

t| _i | _t| | _dS )a ``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 ``dict``. This can be used to provide custom
deserializations (e.g. to support JSON-RPC class hinting).
``object_pairs_hook``, if specified will be called with the result of
every JSON object decoded with an ordered list of pairs. The return
value of ``object_pairs_hook`` will be used instead of the ``dict``.
This feature can be used to implement custom decoders.
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. 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. 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 ``strict`` is false (true is the default), then control
characters will be allowed inside strings. Control characters in
this context are those with character codes in the 0-31 range,
including ``'\t'`` (tab), ``'\n'``, ``'\r'`` and ``'\0'``.
