At the moment "root" works like an "unzip". What you want it is some kind of "up-till-root" shortcut. If "root" changes its meaning, something like "unzip" should be added. (unzip loc) could just be a shortcut for (node (root loc)). I think unzip makes it clear, that we now leave the zipper session, which (node (root loc)) does not. > It would also be nice if the docs mentioned that a loc is a vector of > [node path]. Why do you need to know? > The doc for zipper should also say something like > "Creates a new zipper structure. Returns the loc of the root node. ..." That would be more consistent of with the rest of the documentation.
