It depends upon how you look at them. From the procedural point of view List::Util is a loosely related collection of disparete functions.
If you take the OO view, then Perl's array's are a generic, ordered container class, and List::Util provides a set of extra methods.
If only it were so easy to add a whole raft of new methods to every ordered collection type in the STL's of most other OO languages.
I have to say that List::Util is my all-time, number-one, most used module. The only things it lacks from my perspective are mapn (also known as mapcar) and mapNbyM (to be known as zip in p6).
