`@instanceof` throws fatal error due to documentation example

[codepuncher]

This code:

@instanceof($latest_posts_query, 'WP_Query')
  {!! \App\pagination($latest_posts_query) !!}
@endinstanceof

Renders this code:

<?php if ($latest_posts_query instanceof 'WP_Query') : ?>
  <?php echo \App\pagination($latest_posts_query); ?>

<?php endif; ?>

With the error of Fatal error: Uncaught Symfony\Component\Debug\Exception\FatalThrowableError: syntax error, unexpected ''WP_Query'' (T_CONSTANT_ENCAPSED_STRING).

The documentation of this directive suggests passing the class name as a string but in fact, should be the actual instance object.

Simply removing the quotes around the second argument will fix the issue.
