Hi internals, I'd like to address a common footgun when using foreach by reference: https://wiki.php.net/rfc/foreach_unwrap_ref
This addresses the issue described in the big red box at https://www.php.net/manual/en/control-structures.foreach.php. While this is "not a bug" (as our bug tracker can regularly attest), it's rather unexpected, and we could easily avoid it... Regards, Nikita
