 I put together a patch for this Haskell' proposal
 (http://hackage.haskell.org/trac/haskell-prime/ticket/41)

     Prelude> (if then "Haskell" else "Cafe") False
     "Cafe"
     Prelude> (case of 1 -> "One"; _ -> "Not-one") 1
     "One"

 There seems to be some support for integrating this proposal into GHC (see
 http://permalink.gmane.org/gmane.comp.lang.haskell.cafe/81366)

 The attached patches implement the feature, test it and document it.
