It was surprising to me that is_less_than etc were part of the numeric mix-ins and not part of a more general ordering mix-ins. Many types can be ordered with some combination of __lt__, __gt_, etc magic methods plus functools.total_ordering. I would even suggest that checking that the types of the left-hand and right-hand sides be left up to the the magic method implementation (e.g. a custom _lt_ implementation can check that other matches a supported type or dynamically lookup other's fields).
