$page->get('title'); // works
$page->get('headline|title'); // doesn't work

Setup/Environment

@Toutouwai I'm not so sure on this one, as the a|b|c format is intended to return the first non-empty match (see here). A "0" string is empty, according to PHP. So it's more a question of whether you consider a "0" to be empty or not. PW mostly follows the PHP definitions of things like this, but I can also see how a case could be made that a "0" string has a length of 1, so a 0 as a string isn't really empty...
