The target structure is an array of arrays, see perldsc

You can use splice to extract regions out if the original array (i.e. if you don't want to copy to a new one)

Otherwise just slice and copy.

 $new[$i++] =  [ @old[$start..$end ] ]

edit

And for traversing use a recursive function which calls itself when an array-ref is read.
