+\texttt{unsplit} is an arrow that takes a pair of values and combines them to
+return a single value:
+
+\begin{code}
+unsplit :: (Arrow a) => (b -> c -> d) -> a (b, c) d
+unsplit = arr . uncurry
+ -- arr (\op (x,y) -> x `op` y)
+\end{code}
+
+\texttt{(***)} combines two arrows into a new arrow by running the two arrows on a
+pair of values (one arrow on the first item of the pair and one arrow on the
+second item of the pair).
+
+\begin{verbatim}
+f *** g = first f >>> second g
+\end{verbatim}
+
+Block quote:
+
+\begin{quote}
+foo bar
+\end{quote}
