In the script

#!/usr/bin/perl

use warnings;
use strict;


my $sod='ip6 is used for...';
my $i=0;
my @baza_tek=qw( (?^u:ip(\d)) "internet_protocol-$1$2" );

$sod=~s#$baza_tek[$i]#$baza_tek[$i+1]#gee;

[download]

i have such an error on execution:

Use of uninitialized value $2 in concatenation (.) or string at...

My question is,

How to tell PERL to show the values of current baza_tek[$i] or $baza_tek[$i+1] at the time, when the error occured?
