Another suggestion for you in addition to that from choroba .

C style for() loops are actually quite rare in Perl. They are prone to the dreaded and most common programming error, the "off by one error". Here is another way to write blubb(). 

use strict;
use warnings;
sub blubb
{
        my $array_ref = shift;
        my $i =0;
        
        foreach (@$array_ref) #dereferences the ref to an array
        {
           print $i++, "  $_\n";
        }
        
}
my @array = (1, 2, 3);
blubb([reverse @array]);

__END__
Prints:
0  3
1  2
2  1
