You can use shift operator in this case..

shift operator takes an array, removes an element from the start and updates the existing array

If your array becomes empty, it returns undef, which you can handle

sub average {
    $sum = shift @_;
    while (defined($num = shift @_)) {
        $sum += $num;
    }
}
