Documentation

data Extension

This represents language extensions beyond a base Language definition (such as Haskell98) that are supported by some implementations, usually in some special mode.

Where applicable, references are given to an implementation's official documentation.

Constructors

EnableExtension KnownExtension

Enable a known extension

DisableExtension KnownExtension

Disable a known extension

UnknownExtension String

An unknown extension, identified by the name of its LANGUAGE pragma.
