That the code does what the docs indicate is beside the point (though
it's good that they're in agreement ;-) ). The behavior is definitely
not what I would've expected, which is to return false. My vote is to
just return false when there are no elements. I like to avoid nil
whenever possible (which is almost always) because it forces client
code to use a conditional to check for it.
