When passing a tuple to signing.dumps, I get a list back after calling signing.loads

[lee@…]

>>> from django.core import signing
>>> a = signing.dumps(('a','b','c'))
>>> signing.loads(a)
['a', 'b', 'c']

I'd have expected it to behave the same as pickle:

>>> a = pickle.dumps(('a','b','c'))
>>> pickle.loads(a)
('a', 'b', 'c')

Signing uses JSON to dump and load content, and there is no native distinction in JSON between lists and tuples. I don't know if we can/should do something to fix this, but accepting because it should at least be documented (​https://docs.djangoproject.com/en/dev/topics/signing/#protecting-complex-data-structures).

Fixed #18745 - Documentation change explaining tuple to list with signing.

Thanks to lee for the report.
