[Haskell-cafe] Call to arms: lambda-case is stuck and needs your help

[Christopher Done]

I like \case as is proposed. It seems the least controversial one and
there's curry (\case ) for two-args, but even that seems a rare case.

For what it's worth, I like the idea of omission being partiality, as
in case of and if then. It seems perfectly natural to me, I don't need
a \ to tell me that an expression will result in a function. But some
do. So I'll go along with and vote for \case. The lack of a lambda
case is one of the few "legitimate" complaints I have about Haskell's
syntax so it would be marvey to see it in GHC.

P.S. \if then … else …?
