Absolutely the correct answer.

in thread Linked lists as arrays: inserting values
Building a large data set by repeatedly splicing into the middle is indeed O(n*n) while a linked list is O(n). But that is O(n*n) with a small constant term versus O(n) with a big term. Unless your dataset is very large, the native array approach will be far faster. Just consider the cost of accessing the next element. With the native approach it will be a pointer lookup versus having to make a function call (and Perl function calls are slow).
Furthermore a final reason not to use linked lists in Perl. Unless you are very careful, the linked lists will have circular data structures (each item points to the next which points to the previous). Therefore you are either in the business of having to do memory management yourself, or else you need to add yet another layer of slow indirection. Either way you've added more complexity, more room for bugs, and have reduced your potential performance gains even more.
