src/Data/ByteString/Handle/Read.hs:158:9: error:
    • Couldn't match type ‘()’ with ‘Integer’
      Expected: IO Integer
        Actual: IO ()
    • In a stmt of a 'do' block:
        maybe
          ioe_seekOutOfRange (writeIORef (read_seek_state rs)) newSeekState
      In the expression:
        do size <- getSize rs
           curSeekState <- readIORef (read_seek_state rs)
           let newSeekState = ...
           maybe
             ioe_seekOutOfRange (writeIORef (read_seek_state rs)) newSeekState
      In an equation for ‘seek’:
          seek rs seekMode seekPos
            = do size <- getSize rs
                 curSeekState <- readIORef (read_seek_state rs)
                 let newSeekState = ...
                 ....
