Well, it sounds cute having Neginfinite and Infinite as built-int
objects that can be compared to any other type and are < of or > of
everything else but themselves. Probably they can be useful as
sentinels, but in Python I nearly never use sentinels anymore, and
they can probably give some other problems...
