[Haskell-cafe] Patch for library (new feature) - how to deal with it

Hello, I have written patch (attached) which introduce new API for zlib - personally I wrote it to have easy implementation of compression/decompression in iteratee (example file - no yet working -attached). Earlier version of patch I tried to sent to maintainer of zlib. However I received no response (possibly I get into spam folder by helpful spamassassin or something like that). I definitely don't want to fork this library - especially that it is in haskell platform. What should I do with the patch? Regards
