This works for infinite lists if there is no balancing, but if insert does balancing, the top of the map will not be available until the last key is seen, so splitSeq' could only be used for finite chunks. Then you'll need a way to put the partial answers together. It might be possible to amortize the cost of that for an appropriate choice of chunk length. It would also cost some laziness: the chunked version would work for infinite lists, but wouldn't produce all the output for a partial list. _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
