title: C++: const reference, before vs after type-specifier
body: <p>What is the difference between the arguments in:</p>
  
  <pre><code>int foo1(const Fred &amp;arg) {
  ...
  }
  </code></pre>
  
  <p>and</p>
  
  <pre><code>int foo2(Fred const &amp;arg) {
  ...
  }
  </code></pre>
  
  <p>?
  I don't see this case covered in the parashift FAQ.</p>
