Suppose I have a class which checks whether it knows
how to do a comparison, and if not, wants to pass it
on to the other operand in case it knows:
class Foo:
def __lt__(self, other):
if I_know_about(other):
# do the comparison
else:
return other.__gt__(self)
If the other operand has a __gt__ method which is
doing similar tricks, infinite recursion could result.
