This has been discussed a few times already, and I think that everyone
agrees that this behavior should go, but not necessarily on the migration
path. There is an RFC here: https://wiki.php.net/rfc/on_demand_name_mangling
I think that the latest version of that RFC, that basically proposes to
drop the behavior and tell people to use a polyfill is fine.
