A deep loop over a multidimensional array.
use Enzyme\Loopy\Each;
$array = [1, 2, 3, 4 => [4, 5, 6]];
Each::deep()->begin($array, function($bag) {
echo $bag->value() . ', ';
});The above will output 1, 2, 3, 4, 5, 6,
A loop over a filtered array.
use Enzyme\Loopy\Each;
use Enzyme\Loopy\Filters\SkipNulls;

echo $bag->value() . ', ';
});The above will output 1, 2, 4, 5,

| depth() | Current depth (0 based) | The current depth of the pass, for multidimensional arrays. |
| index() | Current index (0 based) | The current index, in this case index is really a count of the number of items encountered so far. |
