list[-1] maps very well to my mental concept of list. To me 'List' brings to mind a bunch of things in a line. It's intuitive to count forward or backward.
Ruby's 'last' doesn't map as well for me because I don't think of the list as having an attribute of 'last.' Java just annoys me because I can never remember if it is 'size', 'length' or something else. Similarly, Java's conversion operators - string to int or back - are something I am *always* referring to as they just don't fit my mental model. I agree with Kent, it's so subjective, but I've also found that Python hits the right level. -- http://mail.python.org/mailman/listinfo/python-list
