Review Comment:
The problem here is that it becomes a bit ambiguous if we support to take
actual columns instead of just literals in `col2` and `col3`, which actually
happens time to time. Or, e.g., if `col2` and `col3` support other types. Maybe
we should just keep the signature as `ColumnOrName`.
`sentences` is one example.
