    -- | This module is not used by GHC itself.  Rather, it exports all of
    -- the functions and types you are likely to need when writing a
    -- plugin for GHC. So authors of plugins can probably get away simply
    -- with saying "import GhcPlugins".
    --
    -- Particularly interesting modules for plugin writers include
    -- "CoreSyn" and "CoreMonad".
