Code

public function enterNode(Node $node, Environment $env) : Node {
  if ($node instanceof CheckToStringNode) {
    // Replace CheckToStringNode with the faster equivalent, __toString is an
    // allowed method so any checking of __toString on a per-object basis is
    // performance overhead.
    $new = new TwigSimpleCheckToStringNode($node->getNode('expr'));
    // @todo https://www.drupal.org/project/drupal/issues/3488584 Update for
    //   Twig 4 as the spread attribute has been removed there.
