[Haskell-cafe] proposal: point free case expressions

5 Nov 2009

      Hello all,

Wouldn't it be nice if we could write point free case statements?

I regularly find myself writing down something like this:
...
myFunc = anotherFunc $ \x -> case x of
                               Left err -> print err
                               Right msg -> putStrLn msg
We could really use a case statement in which we skip the scrutinee  
and make `(case of {})' be syntactic sugar for `(\x -> case x of {})'.

So we could write:
...
myFunc = anotherFunc $ case of
                         Left err -> print err
                         Right msg -> putStrLn msg
A minor syntactical addition, a big win!

Cheers,
