# Documentation

data Extension #

The language extensions known to GHC.

Note that there is an orphan `Binary` instance for this type supplied by the GHC.LanguageExtensions module provided by `ghc-boot`. We can't provide here as this would require adding transitive dependencies to the `template-haskell` package, which must have a minimal dependency set.
