title: How to write a 'using' statement for enum classes?
body: <p>In a rock, paper, scissors program that I am writing, I am enumerating the three different moves and declaring them as a class. However, when I try to write a using statement so that I have to avoid using the scope operator, it doesn't seem to work. Anyone know why?</p>
  
  <p><code>enum class choice {rock, paper, scissors};</code></p>
  
  <p><code>using namespace choice;</code> </p>
  
  <p>Here an error message comes up, saying: [Error] 'choice' is not a namespace name.
  Why is this? I thought that for choice could be a namespace, in this context.</p>
