New description:
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.
