What do I do to make it happen? I'm not a contributor, so I don't want to even suggest actual code, but it's pretty simple, obviously. > It's also seems like it would have been obvious when creating the > zipper API, so I wonder if it was really an oversight, or actually a > design decision. That was why I asked. I wasn't sure if I was missing something obvious. > Anyway, to "recreate the entire zipper structure" is not a > particularly heavy operation.

Well, in an application, to recreate the structure, one needs to call zip/zipper and pass appropriate parameters. In my case this means I need to create three anonymous functions on the fly and it begins to feel kind of heavy. --J. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
