Supporting negative indices allows right-to-left indexing without having
to find the length of the list.

Not supporting arbitrary indexing allows error detection when the list
does not contain enough elements.

Also, shouldn't this thread be in general, rather than chat?  I thought
chat was supposed to be for non-J related discussion (that happens
to be of interest to people interested in J).
