 Let's take a look and see how Kurtail deals with empty lists. Here we have a list with shape 20 and it has two rows, but they're empty rows. Well, Kurtail will do what it always does, which is to strip off that last row, create a shape of one zero, and that's the result that we get. This next example is a little bit different because it's empty as well, but its shape is zero two, so it has no items. Well, if a shape has no items then Kurtail has no effect on it. So unlike the atom where we had a single item which was itself, if there are no items the result is exactly what is sent in. The Kurtail monadic verb. A monadic verb with infinite rank that returns a list with the last item of its argument removed. I hope after seeing some of these examples you'll have a better sense of how to use Kurtail.
