title: How do I get type parameter from type with type parameter, inside scala macro?
body: <p>I have a type (that, in this case, represents return type of a method), and it is of the form <code>List[Int]</code> (for example).</p>
  
  <p>I know that the type carries that information, because <code>toString</code> results in the proper value, but how can I extract that type? I tried <code>.typeSymbol</code>, but that loses all type information altogether.</p>
