title: How to check if a Stack<T> is empty
body: <p>Is there some other way, except <code>Stack&lt;T&gt;.Count() == 0</code>, to check if a <code>Stack&lt;T&gt;</code> is empty?</p>
  
  <p>Coming from C++/Java background where "stack" classes generally have some sort of dedicated "is empty" method like <a href="http://docs.oracle.com/javase/7/docs/api/java/util/Stack.html#empty%28%29" rel="noreferrer">Java - Stack.empty</a>.</p>
