Hi, Nikita got an idea about stopping changing of array/object internal pointers even in forech by reference. I've added an additional RFC section:
https://wiki.php.net/rfc/php7_foreach#additional_behavoir_change Trivial implementation on top of the main patch: https://gist.github.com/dstogov/63b269207ba0aed8b776 and an additional proposed voting question. Also, the implementation now must be almost complete. Thanks. Dmitry.
