Hmm, though this is actually precisely backwards compared to the stated in Gérard Huet's paper, isn't it? He visualized it working like a zipper, that is opening the tree (unzipping) as one navigates, and then stitching it back together (zipping) on the way back to root. Still, since the data structure is called "Zipper", its understandable to think of its primary action (navigating) as zipping, so returning to the root must then, logically, be "unzipping", which is the opposite of what I argued in the previous paragraph. ;-) And people wonder why it's hard to name things well! // ben --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
