I expect these docs date back to when ints, longs, and floats were the only hashable language-supplied types for which mixed-type comparison could ever return True. They could stand some updates ;-) `fractions.Fraction` and `decimal.Decimal` are more language-supplied numeric types that participate now, and the Boolean singletons are instances of (a subclass of) `int`. I think it would be good to point that out, especially the latter (in many other languages Booleans can't be compared to ints). So +1 both to Mark's more-general explanation, and to explicitly naming more specific cases for illustration.
