I think changing reference is a bad idea, even if it's behind some sort of declare or ini setting or what-have-you.
I do support `inout`, which has similar high-level outcomes: the current value is fed in, and when the function returns it has a new value. I think we should use `&` at the call site, and we should also permit it optionally for by-ref parameters as it provides a migration path: first add `&` to all the call sites, then switch it to `inout`. -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
