> Follow up to ARROW-229. Some projects may reuse temporary buffers, so presuming you know how much memory to allocate, you will want to be able to invoke the cast closures in generic way.
> The API created in doing this should be deemed experimental as we iterate towards a more generic analytical kernel evaluation model
