We should ask the community whether they would mind seeing these extensions vanish and remove them if not. If so then we should see to it that they are registered properly with Cabal so they can be used on Hackage. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/11359> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

Using `-fwarn-missing-monadfail-instance`, GHC's internal warnings created by the patch can be shown and fixed. A second pass with `-XMonadFailDesugaring` then provides a hard check on whether any issues remain, by switching on the new desugaring mechanism properly. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/11091> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
