Altering the Return Value: List Context

        $return = &$original;
        $dummy = scalar $wrapper{post}->(@_, $return)
                if $wrapper{post};
        ...
        return $return;

This code was for scalar context calls
List context is handled similarly

        $return = [ &$original ];
        () = $wrapper{post}->(@_, $return)
                if $wrapper{post};
        ...
        return ref $return eq 'ARRAY' ? @$return : ($return);

The postwrapper gets an extra listref argument
