Just a little correction: __cmp__ is the "old" comparison method, the  
"rich" comparisons are the six __eq__, __lt__, __gt__, ...
(__cmp__ assumes that any object is either equal, or greater, or less than  
another, and no other possibility exists; this isn't true for many  
objects, that's why the "rich" methods had to be introduced).
