[I] Clarify logic in `nth_value` function [datafusion]
alamb opened a new issue, #14063:
URL: https://github.com/apache/datafusion/issues/14063
took me a while to figure out what's happening here; maybe instead check slice.nulls() explicitly and return None if it doesn't exist (i.e. there's no nulls)?
also the pre-existing short-circuiting might be useful in cases where the nulls() index exists but valid_indices() truly is empty (i.e. the array is completely nulls)?
