Another thing is that, for performance reason, even there is only one parameter, it is still a good idea to pass array ref, instead of array.

(davido didn't mention this simply because this was not asked in the original post)

my @numb = (1..100);
print sum(\@numb);

sub sum {
    my $numb = shift;
    my $total;
    foreach (@$numb) {$total += $_};
    return $total;
}
