Hm. cmp is a builtin function. That seems an exceedingly odd place to stick arbitrary constants -- much more so than type objects (like Martin's recently proposed unicode property for controlling error handling).

If the high/low (or hi/lo, Max/Min, etc.) objects themselves are subclasses of object, it may make sense to just place them at object.high/object.low.

One idea was to create a type called 'extreme', bind it to cmp.extreme, and subclass high/low from extreme. Of course that is just one more arbitrary object attached to cmp, which is even more odd.

Another option would be for min.Min and max.Max, but I'm pretty sure that would be confusing.

The convenient part about putting them as attributes of cmp is that it is obvious that they are most useful when it comes to comparing against other objects.
