Well, for what it's worth, my vote goes for a multi-argument \case. I  
find the comment on the wiki page about mistyping "\case Just x"  
instead of "\case (Just x)" a lot a bit disingenuous, since you  
already need these parens with today's lambda. The complaint that  
multi-argument cases are unorthodox doesn't really hold a lot of  
weight with me -- much more serious things than syntax have changed in  
GHC compared to the Report!

Is there a more formal way to cast votes...?
