How do I query list for any matches on item property?
<p>I have a <code>List&lt;Tuple&lt;int, string&gt;&gt;</code>. I want to get a <code>bool</code> indicating whether there is a match on any of the <code>int</code> values. So for example:</p>

<p><code>{1, "Yada"}, {2, "Data"}</code> returns <code>false</code><br>
<code>{1, "Yada"}, {1, "Data"}</code> returns <code>true</code></p>

<p>Can it be done? </p>
