Also you need to get you hand on State# RealWorld either (1) Honestly, by wrapping your code in IO again and using it normally (2) From a copy, via unsafeInterleaveIO (3) From nowhere, via unsafePerformIO

Or you can get it honestly via lifting: liftRawIO :: (State# RealWorld -> (# State# RealWorld, a #)) -> IO a liftRawIO = GHC.IOBase.IO main = liftRawIO rawMain rawMain :: State# RealWorld-> (# State# RealWorld, () #) {- implement rawMain here -} -- ryan
