<p><code>unsplit</code> is an arrow that takes a pair of values and combines them to
|
|
return a single value:</p>
|
|
<div class="sourceCode"><pre class="sourceCode literate haskell"><code class="sourceCode haskell"><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
|
|
unsplit <span class="fu">=</span> arr <span class="fu">.</span> uncurry
|
|
<span class="co">-- arr (\op (x,y) -> x `op` y)</span></code></pre></div>
|
|
<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>Block quote:</p>

<blockquote>
