assignment3 :: (C w, C s) => (a -> b -> c) -> Variable w s a -> Variable w s b -> Variable w s c -> T w s () Source #
arg :: Variable w s a -> Apply w s a Source #
This function allows to generalize assignment2 and assignment3 to more arguments.
You could achieve the same with nested applications of assignment3 (,).
