The function func_get_arg() and func_get_args() should support being called to return references:

function do_something()
{
    $args = func_get_args();

    for ($i=0; $i<count($args); $i++) {
        do_something_with($args[$i]);
    }
}

$ref = new Object();
do_something(&$ref, "String", 0, 1.5);

This function could register a dynamic number of variables to the session (references for the Object!!!), create an array or simple call another function with exactly the same arguments.

I think it should be no problem for func_get_arg[s]() to save references passed to the function. Like

function x($arg1, $arg2)
{
    $args = array(&$arg1, &$arg2);
}

saves $arg1 and $args by reference if they are passed by reference or by value if they are passed by value.

Thank you, looking forward to the new object model in Zend 2!!!
