func_get_arg() does not support references (see example),

$o=1;
test($o);
echo $o;
function test()	{
   $l=&func_get_arg(0);
   $l=2; }

displays 1, should 2, I think it should be possible changing this without impact, if not perhaps a func_get_rarg() be fine

I fear this cannot be done - you should pass a variable by reference from the start, otherwise you will just assign a reference to a copy.

a function func_get_rarg() should avoid this by treating any function parameter as a reference (if possible), moved to feature request

 If I possible, I would like to better understand you statement...here is what I am thinking you mean,
please correct me if I am wrong:
$o=1;
test($o);
echo $o;
function test() {
   $a = &func_get_args();
   /** $a[0] has already been passed as a copy. We have no idea what to reference it back to! */
}
