> Currently there is no simple way of grouping on the whole tuple/element. Right now the
user needs to specify a trivial keyselector which returns the element itself.
> I suggest to add a dedicated method for this functionality.
> For instance if no arguments are passed to the groupBy call it would group on the elements.
