Output for git.master, git.master_jit, rfc.property-hooks: Deprecated: Return type of CustomIterator::current() should either be compatible with IteratorIterator::current(): mixed, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice in /in/S3fTZ on line 37 object(Entity)#1 (1) { ["_properties":protected]=> array(1) { ["foo"]=> string(11) "hello world" } }
