Another groupingReduce overload

Hi guys,

Guava's uniqueIndex methods are pervasive in the code base I am using
to evaluate lambda:,

A groupingReduce overload like this would be very handy:

    public static <T, K> Collector<T, Map<K,T>>
groupingReduce(Function<? super T, ? extends K> classifier) {
        return groupingReduce(classifier, HashMap::new,
Functions.identity(), throwingMerger());

Is it possible to have it? Please? :-)
