Error on import GHC.TypeLits (type (*))

[Tritlo]

This fails to parse, even though it is valid Haskell:

import GHC.TypeLits (type (*))

main :: IO ()
main = return ()

This is only valid if NoStarIsType is enabled, you need to add it to a local ghc-tags.yaml.

EDIT: Ah ok, I see that ghc-tags doesn't recognize NoStarIsType as a valid extension. This needs fixing. For now as a workaround you can add it to the source file as a LANGUAGE pragma.
