Bring back call-time pass-by-reference

Hi,

Although this should be an old hat, I am surprised PHP5 has not fixed
it, let's fix it in PHP6. There are things you can't without call time
pass-by-reference, most of all variables arguments with references.
So, please de-deprecate it.

Thanks much,

Karoly Negyesi

I am feeling froggy.  I will bite.  What can't you do?  I can think of
several really bad things that can happen.  It can't be OOP cause
objects are already always passed by reference.

Dear Brian,

Say, you have a CMS which generally calls some kind of functions and
some of them might need to modify one array the other needs to modify
two arrays... Currently you need to wrap these into a "arguments"
array otherwise func_get_args will butcher your references.

Can you give a short code example of what you want to do?

I try to be constructive here -- I might end up as a moron, I do not
know, sorry -- but what about adding a parameter to func_get_arg to
get the argument by reference?

In PHP6 allow_call_time_pass_reference settings will be removed.

Hi!

But every function knows the number of its own arguments, isn't it?

This behavior has nothing to do with the call-time-pass-reference
settings, func_get_args works this way.

So, you need to relabel this, "func_get_args() should allow arguments to
be passed by reference".  This has nothing to do with call time pass by
reference IMO.
