\verb!unsplit! is an arrow that takes a pair of values and combines
them to return a single value:

\begin{verbatim}
unsplit :: (Arrow a) => (b -> c -> d) -> a (b, c) d
unsplit = arr . uncurry       
          -- arr (\op (x,y) -> x `op` y) 
\end{verbatim}
\verb!(***)! 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}
