Subject: [PHP-DEV] [RFC] Fix "foreach" behavior

Hi,

I'd like to start discussion about fixing inconsistent "foreach" statement
behavior.
The implementation is almost done. It not only fixes inconsistencies in a
defined by RFC way but also improves performance in most usual cases,
because now foreach by value over array doesn't require array duplication.

https://wiki.php.net/rfc/php7_foreach

https://github.com/php/php-src/pull/1034

I'm going to continue work on implementation improvement and may be fixing
related behavior of some internal functions when they used on array
iterated by foreach by reference (e.g. `array_unshift()`). However, the
conceptual behavior defined in RFC is not going to be changed anymore.

Thanks. Dmitry.
