> Project: Spark
> Issue Type: Wish
> Reporter: Jerry Z
>
> To avoid zipping with index and doing numerous mapping and joins, having a
> single method call to map with an additional two parameters (1: list of
> offsets [(-) for lag, 0 for current and (+) for lead])) and (2:default
> value). The other difference to the map function takes an argument of List<T>
> and not just T.
