Is it true that the current list comparison algorithm
goes trough every element doing identity comparison, and
if every element in the first list *is* the element at
the same position in the second list, and the list has
the same size, then lists are considered equal?

If that's true, then I belive there's no reason for
not comparing if the first list *is* the second list at
the top of list_richcompare(), right?
