In the example below, the elements of the `@kk` array are already array references (i.e., scalar values). No need to dereference them to arrays and then copy them into anonymous array constructors to make them array references: just use them directly. `>perl -wMstrict -le "use Data::Dumper; ;; my @kk = ( [ qw(aa bb cc dd) ], [ qw(kk jj ll mm) ], ); ;; my $i = 1; my $arrayref = $kk[ $i ]; ;; print Dumper $arrayref; print @$arrayref; " $VAR1 = [ 'kk', 'jj', 'll', 'mm' ]; kkjjllmm` [download]	[reply] [d/l] [select]

>perl -wMstrict -le

 my @kk = (
   [ qw(aa bb cc dd) ],
   [ qw(kk jj ll mm) ],
   );

 my $i = 1;
 my $arrayref = $kk[ $i ];
 ;;
 print Dumper $arrayref;
 print @$arrayref;
"
$VAR1 = [
          'kk',
          'jj',
          'll',
          'mm'
        ];
