<p>The most common web code you will ever write is testing your parameters.
You might as well have a good way to do this.</p>
<h2><a name="in_the_old_ages"></a>In the old ages</h2>

<p>Way back then, we used to write code to check all of our arguments.</p>
<p>If we had a route that includes some ID, we would check that we
received it and that it matches the type we want. We would then decide
what to do if it doesn't match. Over time, we would clean up and
refactor, and try to reuse the checking code.</p>
<p>For example:</p>
<pre class="prettyprint">use Dancer2;
