Duplicate of "wontfix" #6574, but I would also appreciate having an is_not_in()
expression. It would be convenient/ergonomic. But if the rationale from the other issue holds, should I submit an issue to remove is_not_null()
?

Darn, well I guess I'll ask again and see if they'll reconsider
from polars.
We will not add this, for the reasons mentioned in the linked issue.
If you don't like negating with ~
you can also use not_
, e.g. pl.col(...).is_in(...).not_()
.
is_not_null
is there because it is a (free) represention of the underlying validity buffer. We may remove it when we have sufficiently improve our IR.
