[Python-Dev] Python semantic: Is it ok to replace not x == y with x != y? (no)

[Adam Bartoš]

Hello,

the comparisons >=, <=, >, < cannot be optimized this way. Not every order
is a total order. For example, sets a = {1, 2} and b = {2, 3} are
incomparable (in the sense that both a >= b and a <= b is False), and it is
no pathology.
