Hi, if I have an array of array refs, for example: 
 my @un_sorted = ([3,4,23,4,5],[3,4,56,2,4],[2,3,43,5,3],[2,3,43,6],[3
+,4]);

How do I sort by the first column, then 2nd, 3rd, etc. In my situation, I actually don't know how many columns, and each row may have different sizes. I'd like the result to be: 
2,3,43,5,3
2,3,43,6
3,4,23,4,5
3,4,56,2,4
3,4
