GHC.LanguageExtensions.Type

A data type defining the language extensions supported by GHC.

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.
