    -- | This module re-exports the 'Extension' type along with an orphan 'Binary'
    -- instance for it.
    --
    -- Note that the @ghc-boot@ package has a large set of dependencies; for this
    -- reason the 'Extension' type itself is defined in the
    -- "GHC.LanguageExtensions.Type" module provided by the @ghc-boot-th@ package,
    -- which has no dependencies outside of @base@. For this reason
    -- @template-haskell@ depends upon @ghc-boot-th@, not @ghc-boot@.
