title: Naming convention for Scala constants?
body: <p>What is the naming convention for Scala constants? A brief search on StackOverflow suggestions uppercase CamelCase (the first line below), but I wanted to double-check.</p>
  
  <pre><code>val ThisIsAConstant = 1.23
  val THIS_IS_ANOTHER_CONSTANT = 1.55
  val thisIsAThirdConstant = 1.94
  </code></pre>
  
  <p>Which is recommended Scala style?</p>
