# Regression test for a bug caught during code review of the PR adding this
# func. We insert 3 things in a single persist batch where the least and
# greatest values are valid, but the middle one isn't (so it gets mapped to
# null). The bug was that the interpret would incorrectly conclude that none of
# the values in the batch could be NULL.
