json.load() can raise undocumented RecursionError #135835
Description
json.load() documentation lists JSONDecodeError and UnicodeDecodeError as the exceptions that can be raised.
But in https://news.ycombinator.com/item?id=44344864 it was noted that RecursionError is possible too:
>>> import json
>>> json.loads('[' * 9999)
Traceback (most recent call last):
File "<python-input-1>", line 1, in <module>
json.loads('[' * 9999)
~~~~~~~~~~^^^^^^^^^^^^

obj, end = self.raw_decode(s, idx=_w(s, 0).end())
