Comment (by jrf):

 Note: this is the only code within WordPress which is affected by this PHP
 7.4/8.0 change based on an analysis done by Nikita Popov of PHP core
 before this change was implemented.
 See:
 * http://news.php.net/php.internals/105442
 * https://gist.github.com/nikic/a4df3e8e18c7955c2c21cf6cdb4cbfaa

 FYI: there will soon be a sniff available in
 [https://github.com/PHPCompatibility/PHPCompatibility PHPCompatibility] to
 detect code affected by this change so userland code/plugins/themes can
 verify whether they are affected.
