Description
A PointedList tracks the position in a non-empty list which works similarly to a zipper. A current item is always required, and therefore the list may never be empty. A circular PointedList wraps around to the other end when progressing past the actual edge.
Install
From pkgsrc-wip (no binary package):
cd /usr/pkgsrc/wip/hs-pointedlist03 && make install clean
