title: Meaning of = delete after function declaration
body: <pre><code>class my_class
  {
      ...
      my_class(my_class const &amp;) = delete;
      ...
  };
  </code></pre>
  
  <p>What does <code>= delete</code> mean in that context?</p>
  
  <p>Are there any other "modifiers" (other than <code>= 0</code> and <code>= delete</code>)?</p>
