mapM_ :: Monad m => (a -> m b) -> Stream m a -> m ()vector-stream Data.Stream.Monadic Execute a monadic action for each element of the Stream
mapM_ :: (Foldable t, Monad m) => (a -> m b) -> t a -> m ()calligraphy Calligraphy.Prelude Map each element of a structure to a monadic action, evaluate these actions from left to right, and ignore the results.

Apply a monadic action to each element of the stream and discard the output of the action. This is not really a pure transformation operation but a transformation followed by fold.
