Hello all, This 16-year old commit () allows an object's state to be updated using its slots instead of its __dict__ at unpickling time. To use this functionality, the state keyword-argument of Pickler.save_reduce (which maps to the third item of the tuple returned by __reduce__) should be a length-2 tuple. As far as I can tell, this is not mentioned in the documentation (). I suggest having the docs updated. What do you think? () https://github.com/python/cpython/commit/ac5b5d2e8b849c499d323b0263ace22e56b4f0d9 (**) https://docs.python.org/3.8/library/pickle.html#object.__reduce__

Hello all,
This 16-year old commit (*) allows an object's state to be updated
using its slots instead of its __dict__ at unpickling time. To use this
functionality, the state keyword-argument of Pickler.save_reduce (which maps to
the third item of the tuple returned by __reduce__) should be a length-2 tuple.
As far as I can tell, this is not mentioned in the documentation (**). I suggest having the docs updated. What do you think?
