As doing IO in the CGI Monad is a current need, it's an instance of
MonadIO and as such provide liftIO, so your arcaneMagic is called
liftIO :
cgiMain :: CGI CGIResult
cgiMain = do
inp <- getInput "id"
gen <- liftIO $ parse inp
output $ take 10 (randoms gen)
parse :: Maybe String-> IO StdGen
parse (Just x) = return $ read x
parse Nothing = getStdGen
