<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>&gt; unsplit :: (Arrow a) =&gt; (b -&gt; c -&gt; d) -&gt; a (b, c) d
&gt; unsplit = arr . uncurry       
&gt;           -- arr (\op (x,y) -&gt; 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 &gt;&gt;&gt; second g
</code></pre>
<p>Block quote:</p>
<blockquote>
<p>foo bar</p>
