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.

[2] http://hackage.haskell.org/trac/ghc/ticket/4359
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)).
