I have a zipper and here's the code I'm trying to execute: 1) search through all nodes until a match for a predicate is found 2) starting at that node go up to its parent then mark all children of the parent with extra info 3) the parent has the option to go to it's parent and perform step 2 as well 4) go back to the node marked in (1) and continue execution, but with the latest version of the zipper as defined by (2) and (3)
Since zippers use immutable data I can't simply go back to the data in 1 as then I'll loose my changes. Is there currently some way to save the path to the current node and then later reset to root and replay the zipper commands to get back to that node?
