Yes. Those two were on my list initially, but then I tried to figure out 
how using a slice would actually *work* for them. At which point, I took 
them back off the list - slice arguments just didn't make any sense.

So I think we're down to two things to implement - list.pop and 
array.pop. As you say, UserList.pop should just be a different way of 
spelling list.pop.

Cheers,
Nick.
