Is there a definitive (maybe even formal?) description of the change to the language embodied by each of these extensions? If not, then it is going to be difficult for implementations other than ghc to implement them.

Most, but not all are documented in the GHC users guide. It would not be unreasonable to ask for a proper description of the remaining ones. http://haskell.org/ghc/docs/latest/html/users_guide/ghc-language-features.ht... Unfortunately the user guide does not make it entirely clear what language extension name to use in each case. http://www.haskell.org/ghc/docs/latest/html/users_guide/flag-reference.html#... Personally I would quite like to include documentation and a little example for each one in the Language.Haskell.Extension haddock docs. That would be a useful reference for users trying to figure out which extension it is they need to enable. Duncan
