Store an \SplPriorityQueue

[soyuka]

Is it expected to loose informations about the \SplPriorityQueue? (haven't tried with other SPL classes)

$bar = new \SplPriorityQueue();
$bar->insert('a', 1);
var_dump($bar);
apcu_store('foo', $bar);
var_dump(apcu_fetch('foo'));

apcu supports any class that can be serialized, and it looks like SplPriorityQueue currently doesn't support this. I've filed an issue with PHP here: https://github.com/php/php-src/issues/14402
