I didn't see any mature zipper libraries to efficiently manipulate trees. Can you point me to any mature libs ?
There's http://hackage.haskell.org/package/rosezipper for Data.Tree and http://hackage.haskell.org/package/zipper for generic data types. Not sure if they count as "mature", but zippers are straightforward to implement anyway. You could even roll your own, it's very simple. Regards, Heinrich Apfelmus -- http://apfelmus.nfshost.com
