I'm just wondering, how is it possible that this got changed when the only
RFC mentioning this change got rejected (
https://wiki.php.net/rfc/reflectiontypeimprovements )? I don't see any
consensus in the later discussion so unless I missed something, which is
quite possible, this change should not be there in the first place, right?

Cheers
