 When I say

 {{{#!hs
 module Bug where

 foo = \case True -> False
             False -> True
 }}}

 I get

 {{{
 Bug.hs:9:7: error: parse error: naked lambda expression ''
 }}}

 We can do far better. Setting priority to high because it's rather
 embarrassing to let your lambdas run around naked.
