Wouldn't this fail if the same element appears mulitple times in an array, such that the number of times it appears overall is == num of arrays? This code assumes all elements are unique in each array.

The next solution has the same assumption.

A quick look at the source of List::Compare leads me to think it does not make that assumption.
