title: Different enums, same value
body: <p>Is it possible to make two different enums with a same value?
  For example,</p>
  
  <pre><code>enum direction{
      LEFT,
      RIGHT,
      UP,
      DOWN,
      NONE
  }
  enum color{
     RED,
     GREEN,
     BLUE,
     NONE
  }
  </code></pre>
  
  <p>The compiler would say that there are two declarations of 'NONE'.
  Is there a way around this?</p>
