\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}
