Generally sympathetic to this change, less parenthesis are good. For lambdas it looks a bit unusual, but I think I’d quickly adjust to parsing

Minor comment: In the wiki page you include `{-# SCC #-}` and `{-# CORE
#-}`. I’d doubtful about them. I mentally parse them not as control structures, but as if they were normal functions (which happen to only work when used fully applied), and would be surprised if `f a b {-# SCC #-} d e` turn into `f a b ({-# SCC #-} d e)`. Yes, I think that makes sense. Thank you for pointing it out. I just moved `SCC` and `CORE` from the main proposal to the "Design Space" section. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10843#comment:21 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
