Is there any version of Haskell (Hugs or Ghc) which includes the new notation of arrows introduced by Ross Paterson ? Instead, where can I get it ? The Control.Arrow.hs file did not include the new notation of arrows.
It's supported by GHC 6.2 and later, with the -farrows option (see the GHC User's Guide). To use arrow notation with Hugs or any other Haskell implementation, you need the arrows preprocessor (http://www.haskell.org/arrows/download.html).
