 *  <code>
 *    class MyList[@specialized T] ...
 *  </code>
 *
 *  Type T can be specialized on a subset of the primitive types by
 *  specifying a comma-separated string argument:
 *
 *  <code>
 *   class MyList[@specialized("Int, Double, Boolean") T] ..
 *  </code>
 *  Only primitive types are supported and no name resolution is currently
 *  done on the string arguments (meaning imports and type aliases are
