    Update default-language & avoid default-extensions (#3880) · f87738df
    Herbert Valerio Riedel authored
    This upgrades the `default-language: Haskell98` to `Haskell2010`
    and removes `default-extensions: RankNTypes, FlexibleContexts`
    in favor of adding `LANGUAGE` pragmas where needed.
    
    Moroever, this also drops `LANGUAGE` pragmas which have become redundant
    due to `Haskell2010` (specifically, `EmptyDataDecls`,
    `ForeignFunctionInterface` and `PatternGuards`)
    
    Finally, an `other-extensions` specification is put in place for the
    `Cabal` library component.
    
    This helps loading up files directly in GHCi, such as e.g. `ghci Setup.hs`
    without having to specify `-X...` flags.
