It's not a good idea to deprecate the function
func_get_args/func_num_args() because it is used in user land code to
detect if a function was called with a specific argument like the following:

function (&$argByRef = null) {
    if (func_num_args() > 1) {
        // do expensive stuff to set $argByRef
        $argByRef = true;
    }
    return false;
}
