        # Example of dereferencing in Perl
        my $array_ref = [1, 2, 3];
        print $array_ref->[0]; # Outputs: 1

        # Alternative using dereferencing with curly braces
        print ${$array_ref}[1]; # Outputs: 2

        # Using the map function as an alternative
        my @processed = map { $_ * 2 } @$array_ref; # [2, 4, 6]
