Subject: Allow func_get_arg(s) to pass by reference
From: karoly@negyesi.net ("Karoly Negyesi")

Hi,

I have failed the "state the goal and not the task" rule, sorry.

So, my goal is to pass a variable number of arguments of which some
could be references. I believed that this needs calltime by-ref calls
but obviously need. For func_get_arg, a simple flag could suffice. For
func_gets_args, I do not really know -- maybe a param to take all by
ref, similar to EXTR_REFS.

Thanks,

Karoly Negyesi
