The type signature of mapM_ is currently:

mapM_ :: (Monad m, Vector u a, Vector v b, Vector u c, Vector v d) => ((a, b) -> m (c, d)) -> Vector u v (a, b) -> m ()

It should be

mapM_ :: (Monad m, Vector u a, Vector v b) => ((a, b) -> m c) -> Vector u v (a, b) -> m ()

And forM_ has the same issue.
