Hello again Armin,

Ok, then the current situation looks like the best one. I suggest we just drop a note in the documentation saying that if there are objects for which x.eq(x) isn't necessarily true, you shouldn't expect them to be handled in a fully consistent way.

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?
