Thank you blockhead, I've been playing a bit with Dive. This would be part of a script were data is fed to @MDAsomeIndex in the form +1. I do not not have it behaving this way: 
#!/usr/bin/perl -w
use strict;
use Data::Diver qw[Dive DiveVal];
use Algorithm::Loops 'NestedLoops';

my @MDA;
my $dimension = 3;
my $depth = 2;


NestedLoops(
    [ ( [0..$dimension-1] ) x $depth ],
        sub {
        DiveVal( \@MDA, @_ ) = 0;
        }
    );

$MDA[0][0] += 1;

my @AoA;
for my $level (0..$dimension-1) {
NestedLoops(
    [ ( [0..$dimension-1] ) x ($depth-1) ],
        sub {
            my @indices = @_;
            my $val = Dive( \@MDA, @indices );
            push @{$AoA[$level]}, @$val;
            }
        );}

for my $row (0..$#AoA) {
    print "@{$AoA[$row]}\n";
    }

Prints:
1 0 0 0 0 0 0 0 0

1 0 0 0 0 0 0 0 0

Updated: Expected:
