  // [cfe] Can't access 'this' in a field initializer to read 'staticFun'.

  // The following is a bit tricky. It is a compile-time error to
  // refer to this (implicitly or explicitly) from an initializer.
  // When we remove the line with moreStaticFun, staticFun is really a
  // static function and it is legal to call it. This is what will
  // happen in the /none version of this test. However, in /01,
  // staticFun isn't really a static function and should cause a
  // compile-time error.
