Documentation
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.
