I'm not sure it's acceptable to just throw an UnsupportedOperationException
from listIterator(). ListIterator is supposed to be SUPPORTED by any class
that implements List.
Another way to imeplement ListIterator is to forward all calls to previous(),
hasPrevious() etc. to the "selfIterator", then have set(Object) and
add(Object) throw the exception.
I actually did it, just after sending you the code for iterator()... Do you
