title: Creating a set<char> in C++
body: <p>I am coding this thing and it would be helpful to have a <code>static const set&lt;char&gt;</code> containing some elements that won't change.</p>
  
  <pre><code>class MyClass {
       private:
           static const set&lt;char&gt; mySet = ??  
  }
  </code></pre>
  
  <p>How can I do this? It would be nice if you could create them from a string, like <code>mySet("ABC")</code>, but I can't get the syntax to work.</p>
