Actually, it outputs "90\n". There is no reason why
the list in a 'for' loop cannot iterate over just one item.
In fact, it can make testing easier by allowing us to
substitute a list with just one test item.
foreach my $item ( @very_large_array ) {
print "$item\n";
}
Can be replaced with this for testing:
foreach my $item ( $single_test_item ) {
print "$item\n";
}
