Would it be ok to state that:1) <, >, ==, >=, <=, and != compare the values of two objects;2) the two objects don't necessarily have to be of the same type;3) with == and !=, objects of different types compare unequal, unless they define a specific __eq__ and/or __ne__;4) with <, >, <=, and >=, the comparison of objects of different types raises a TypeError, unless they define specific __lt__, __gt__, __le__, and __ge__;5) some built-in types define these operations, so it's possible to compare e.g. int and floats;This should summarize the possible behaviors.  There's no reason IMHO to expose implementation details and to special case built-in types (unless their comparison is actually different and doesn't depend on __eq__, __ne__, etc.).
