Tweet object fails to unpickle with built-in pickle

[achimgaedke]

The code (python 3.11 and tweepy 4.12.1):

import tweepy
t = tweepy.Tweet(data={'edit_history_tweet_ids': ['16213149247090909'],
                       'id': '16213149247090909',
                       'text': "We're super excited to not only welcome the Flamingo Janes in..."})

import pickle
pickled_tweet = pickle.dumps(t)
pickle.loads(pickled_tweet)

fails with a recursion error and is related to bug #1792 .
(Why not using the data attribute to serialise the object? Initially I wasn't sure whether data contains actually the full state of the object... would be great to clarify in the docs.)

RecursionError: maximum recursion depth exceeded

Reading https://docs.python.org/3/library/pickle.html#pickling-class-instances, I can re-create this by using

obj = tweepy.Tweet.__new__(tweepy.Tweet)
obj.__dict__.update(t.__dict__)

Fixed with #2060

As discussed in that issue, the use case for this is unclear.

Tweet.data is documented.
