Simply: I would like to have direct access into several places in a very long list.
Maybe you could use a zipper. Or just maintain the list split into chunks. So l' = [stuffBefore,hi,stuffAfter]. Or if you want to be able to use each element of hi as a kind of pointer, then l'=[stuffBefore] ++ map (:[]) hi ++ [stuffAfter]
Now modification becomes just a matter of replacing the appropriate chunk. Twan _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
