unsuitable. It seems that a Map Int (Map Int a) is the most suitable structure, but this seems cumbersome.
You might want to use IntMap, which is a version of Map specialised to Int's, with better time bounds. Thanks Neil _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
