New submission from Pierre Glaser <pierregla...@msn.com>:
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?
