source :: Text
source =
  T.unlines [
      "double mean(double sum, double count) {"
    , "    return sum / count;"
    , "}"
    , ""
    , "double max(double x, double y) {"
    , "    return x > y ? x : y;"
    , "}"
    ]

mean :: Double -> Double -> IO (Either JetskiError Double)
mean sum count =
  runEitherT $ withLibrary [] source $ \library -> do
    mean <- function library "mean" retDouble
    mean [argDouble sum, argDouble count]
