> Assignee: Manu Zhang
>
> {{FoldFunction}} is a more general case of the existing {{ReduceFunction}}.
> It allows users to combine input values and put it into an accumulator (e.g.
> {{Collection}}). Without it, we have to firstly map an element to a
> collection and reduce over all collections, which is verbose and inefficient.
