<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 literatehaskell"><code class="sourceCode literatehaskell"><div class="sourceLine" id="1" href="#1" data-line-number="1"><span class="ot">> unsplit ::</span> (<span class="dt">Arrow</span> a) <span class="ot">=></span> (b <span class="ot">-></span> c <span class="ot">-></span> d) <span class="ot">-></span> a (b, c) d</div>
<div class="sourceLine" id="2" href="#2" data-line-number="2"><span class="ot">></span> unsplit <span class="fu">=</span> arr <span class="fu">.</span> uncurry</div>
<div class="sourceLine" id="3" href="#3" data-line-number="3"><span class="ot">></span> <span class="co">-- arr (\op (x,y) -> x `op` y)</span></div></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>

<p>foo bar</p>
