#18745 closed Bug (fixed)

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

>>> 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')
