I'm disputing that chained comparisons are used for the particular combinations that I am actually arguing should not be used in python. Such as a < b > c or a != b != c [whereas a may or may not be equal to c] or a in b in c. Your claim seemed to be that these combinations *are* used, since you claimed that python implements the *same* semantics. -- https://mail.python.org/mailman/listinfo/python-list
