\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}
|
|
|
|
\end{document}
