Hi.
After 21 months of occasional arguing the lambda-case proposal(s) is in danger of being buried under its own trac ticket comments. We need fresh blood to finally reach an agreement on the syntax. Read the wiki page[1], take a look at the ticket[2], vote and comment on the proposals!
P.S. I'm CC-ing Cafe to attract more people, but please keep the discussion to the GHC Users list.

Preliminary votes: * LambdaCase \case: 3 (Christopher, Felipe, Gábor) * LambdaCase \of: 1 (Edward) * MultiClauseLambdas \of: 1 (Daniel) * MultiClauseLambdas with \ in each clause: 1 (Donn) * MultiClauseLambdas with layout rules tweaking: 1 (Tyson) Note that LambdaCase variants do /not/ require parentheses around patterns while MultiClauseLambdas variants do. Did I forget/misunderstand someone? It would be great to have GHC HQ input on the new proposals (layout rules tweaking (Tyson) and case comma sugar (Edward)).
