> CQL functions unnecessarily deserialize their terminal arguments on every
> call.
> For example, the function call in {{SELECT mask_inner(column, 1, 0) FROM t}}
> deserializes {{1}} and {{2}} for each returned row. As another example, the
> selector in {{SELECT column * 2 FROM t}} also deserializes {{2}} for each
> returned row.
> The goal of this ticket is to improve the function execution code to avoid
> those deserializations.
