title: foreach loop with a where clause
body: <p>I was wondering if it's possible to create a foreach loop in <code>C#</code> with a where loop. Not with a if statement inside, but and where clause in the declaring of the loop.</p>
  
  <p>Maybe something like this?</p>
  
  <pre><code>foreach(var n in people where n.sex == male)
  {
  }
  </code></pre>
