title: Get min / max value of a static constexpr array at compile time
body: <p>Let's say I have an array of integers defined like that:</p>
  
  <pre><code>static constexpr int IntArray[] = {1, 5, 10, 12, 17};
  </code></pre>
  
  <p>Is there a way to get the minimum or maximum value at compile time?</p>
