title: Polyphonic C# methods separated by ampersand?
body: <p>I'm reading <a href="http://research.microsoft.com/en-us/um/people/nick/polyphony/intro.htm" rel="noreferrer">this introduction to Polyphonic C#</a> and the first page contains this example:</p>
  <blockquote>
  <p><strong>Example: A Simple Buffer</strong></p>
  <p>Here is the simplest interesting example of a Polyphonic C# class:</p>
  <pre><code>public class Buffer {
      public String get() &amp; public async put(String s) {
          return s;    
      } 
  }
  </code></pre>
  </blockquote>
  <p>I don't get it at all.<br />
  What does the <code>&amp;</code> between methods <code>get()</code> and <code>put()</code> signify?</p>
