title: Quickest way to enumerate the alphabet
body: <p>I want to iterate over the alphabet like so:</p>
  
  <pre><code>foreach(char c in alphabet)
  {
   //do something with letter
  }
  </code></pre>
  
  <p>Is an array of chars the best way to do this? (feels hacky)</p>
  
  <p>Edit: The metric is "least typing to implement whilst still being readable and robust"</p>
