Didn't know that, thanks! But then I'm wondering how they can do parsing and type checking with GHC when they are using their own dialect, "Mu". How come GHC can parse that?

The differences between Mu and Haskell are not that large. They use GHC as a library in their front end. Gergo Erdi gave a talk on it last year:

GHC has a system for language extensions so they have developed a few proprietary ones for Mu. For the standard ones, see https://downloads.haskell.org/ghc/latest/docs/users_guide/ex...
