In response to Initializing multidimensional arrays, I wanted to come up with a general solution: given an initialization value and the dimensions, initialize an array. Here's what I came up with: 
use Algorithm::Loops 'NestedLoops';
use Data::Dumper;

sub init_arr {
    my ($val, @dims) = @_;
    my $arr;
    NestedLoops( [map [0..$_-1], @dims], sub {my $r = \$arr; map {$r=\
+(($$r)->[$_])} @_; $$r=$val} );
    $arr;
}

print Dumper (init_arr('hi',3,2,1));

It works, but it seems like there should be a way to track my current position in $arr. I'm having to follow the chain of refs through all dimensions on each iteration. How would you do it?

Update: I'd really like to see an example using Algorithm::Loops 'NestedLoops'. This isn't something I'm doing because I need the task accomplished, it's a learning thing.
