title: Lambda: uncaptured objects in unevaluated context
body: <p>I'd appreciate a pointer to the Standard paragraph stating that the <a href="https://wandbox.org/permlink/IgTZSwWG1O2BAzy5" rel="nofollow noreferrer">following code</a> is well-formed:</p>
  
  <pre><code>int main() {
      int var = 0;
      return [] { return sizeof(var); }(); // var is not captured!
  }
  </code></pre>
  
  <p>Similar example appears e.g. in § 8.4.5.2, but I could not find any verbal description of it. </p>
