title: Is there a way to specify a default value for python enums?
body: <p>Given the following enum:</p>
  
  <pre><code>class MyEnum(IntEnum):
  
      A = 0
      B = 1
      C = 2
  </code></pre>
  
  <p>How can I specify a default value. I want to be able to do:</p>
  
  <pre><code>my_val = MyEnum()
  </code></pre>
  
  <p>and have<code>my_val</code> be <code>&lt;MyEnum.A: 0&gt;</code></p>
  
  <p>Is this possible? I've tried customizing <code>__new__</code>, <code>__init__</code>, <code>__call__</code> but I can't get it to work.</p>
