Do the higher order functions only work on lists right now? For example,
can I reduce a map? If not, we can tackle later, but just want to understand
the scope.

> Issue Type: Improvement
> Reporter: Casey Stella
>
> To enable use-cases where the user may want to do simple iteration, we can
> expose simple functional primitives such as:
> * MAP
> * REDUCE
> * FILTER
> To fully support this, we will need lambda expressions as arguments to these
> functions.
