Yep but the given/when is DRYer because you don't need to repeat the $grade eq

re: smart match & more complicated than `eq` - Yes you can push given/when quite a bit:

    given (TheTime->of_day) {

        when ('morning') {
            breakfast();
            make_packed_lunch() if $_->is_work_day;
        }

        lunch() when 'afternoon';

        when ('evening') {
            goto_pub() if $_->is_friday;
            dinner();
        }

        default { say "Should be sleeping if its " . $_->{dt}->ymd }
    }
