4. Rejigger Partition to return an array again, with an explicit lambda (which will likely be an array ctor ref) to make the array. Eliminated the silly Partition class. Please don't do that, it's pure evil. public static Collector<T, Collection[]> partitioningBy(Predicate predicate, IntFunction<Collection[]> arraySupplier) {
