<p><code>unsplit</code> is an arrow that takes a pair of values and combines them to return a single value:</p>
|
|
<pre class="sourceCode literate haskell"><code>> unsplit :: (Arrow a) => (b -> c -> d) -> a (b, c) d
|
|
> unsplit = arr . uncurry
|
|
> -- arr (\op (x,y) -> x `op` y)
|
|
</code></pre>
|
|
<p><code>(***)</code> 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).</p>
|
|
<pre><code>f *** g = first f >>> second g
|
|
</code></pre>
