dragonchild,
Sure List::Util has shuffle() but how does this meet the requirement. Perhaps I am misreading it or perhaps the root thread was updated after you replied but I believe the requirement also mandates that elements not remain in their original position. This is a derangement and I think that Derangement of a list and Derangements iterator are probably more applicable. I also see that frenchtoast had the same idea elsewhere in the thread.

Cheers - L~R
