in thread The maybe it is better written this way tool

I think Anonymous Monk make hints about $[ 

$[ = 10;
my @arr = ('a', 'b');
use Data::Dumper;
warn Dumper [ $#arr, scalar @arr ];
__END__
$VAR1 = [
          '11',
          2
        ];

Actually I think it would be better if this tool will suggest not to change $[ in the first place.

    So you'rehe's saying I shouldn't do the following? 

    for my $i (0..$#array) {
   ...
}

    No. The proper answer is not to avoid $#array, it's to avoid $[.

    $[ has long been discouraged, it is deprecated in 5.12, and it will be removed for 5.14.
