Args:
s_and_end (tuple): A tuple containing the input string to parse and the current index within the string.
strict (bool): If `True`, enforces strict JSON string decoding rules.
If `False`, allows literal control characters in the string. Defaults to `True`.
scan_once (callable): A function to scan and parse JSON values from the input string.
object_hook (callable): A function that, if specified, will be called with the parsed object as a dictionary.
object_pairs_hook (callable): A function that, if specified, will be called with the parsed object as a list of pairs.
memo (dict, optional): A dictionary used to memoize string keys for optimization. Defaults to None.
_w (function): A regular expression matching function for whitespace. Defaults to WHITESPACE.match.
_ws (str): A string containing whitespace characters. Defaults to WHITESPACE_STR.
Returns:
tuple or dict: A tuple containing the parsed object and the index of the character in the input string
after the end of the object.
