Hi Stan,
There is a use case for the function allowing *explicitly* call-time pass
by reference, because the function works both ways in subtly different
ways.
This RFC isn't about whether or not this behaviour should be deprecated. It
simply recommends that a warning be thrown by default in PHP 5.3 so that
people will know to fix their code. The rationale for this is that there is
ALWAYS a warning thrown in PHP 6, with no possibility to avoid that warning.
It is also still marked deprecated in PHP 6, i.e. there is presumably a firm
intention to remove the possibility for call-time pass-by-ref altogether.
call_time_pass_by_reference behaviour has been deprecated for 8 years plus -
since before the PHP 4.0 release. If you're writing code that relies on that
behaviour, either you don't care about the warning or you've never seen it.
I suspect rather a lot of PHP users have never seen it, because by default
that warning isn't thrown at all.
If you want to argue that there should be no warning by default, fine. But
please try to stay on-topic.
Thanks,
- Steph
