When I see this I come to think about if this might have helped
with upgrading to PHP 7 from PHP 5 due to the RFC:
- https://wiki.php.net/rfc/counting_non_countables

Like:
$value = $countvalue?->count($countvalue);

Even if I solved over 90% replacing count with empty there could
be a few more places where this might prove handy. So +1 on this!
