>
> All four kernels (and soon to be fill_null_forward/backward) make use of a
> set of very similar utilities for copying data between arrays; we should
> consolidate those into a single set of helpers instead of duplicating them,
> and consider whether they could be further consolidated (e.g. making use of
> the FixedWidthType hierarchy instead of specializing for every type)
