title: Is changing the number of an enum a breaking change?
body: <p>Consider the following code:</p>
  
  <pre><code>public enum SomeCode
  {
       NIF = 0
      ,NIE = 1
      ,CIF = 2
      ,PAS = 3
      ,NIN = 4
      ,SSN = 5
      ,OTH = 5
      ,UKN = 6
  }
  </code></pre>
  
  <p>Would changing <code>OTH = 5</code> to <code>OTH = 7</code> be a breaking change?</p>
  
  <hr>
  
  <p>Edit: I never store the int value, only ever the text representation of the enum.  It may be used in other DLLs, but will use the same storage.</p>
