59\texttt{unsplit} is an arrow that takes a pair of values and combines them to
63unsplit :: (Arrow a) => (b -> c -> d) -> a (b, c) d
64unsplit = arr . uncurry
65 -- arr (\op (x,y) -> x `op` y)
68\texttt{(***)} combines two arrows into a new arrow by running the two arrows on a
69pair of values (one arrow on the first item of the pair and one arrow on the
70second item of the pair).
