Perhaps knocking up a some reusable utility methods along these lines would
be enough?
public static ListIterator<T> getListIterator(Sequence<T> sequence) {...}
public static Iterator<T> getIterator(Sequence<T> sequence) {...}
public static Iterable<T> getIterable(Sequence<T> sequence) {...}
I'm not aware of anything like this within Pivot, but may be wrong.
