There is an off-by-one error in your translation, Limbic~Region. The P6 version is missing the first group because you used pre-increment rather than post-increment on $iter. This will correct the problem: 
    my $iter = -1;

I'm hoping to create a version soon that can handle this example from the NestedLoops documentation: 

    use Algorithm::Loops qw( NestedLoops );
 
    my $depth= 3;
    NestedLoops(
        [   [ 0..$N ],
            ( sub { [$_+1..$N] } ) x ($depth-1),
        ],
        \&Stuff,
    );

In other words, a full implementation should allow code refs for the ranges, not just fixed ranges.
