Review Comment:
I think the key to success is to have some kind of syntax for quoting
literals. For example:
https://spark.apache.org/docs/latest/sql-ref-literals.html
Then we can parse something like:
```python
'a.b' -> Reference(('a.b',))
'a.b'.c -> Reference(('a.b', 'c'))
a.b.c -> Reference(('a', 'b', 'c'))
```
Or folks have to use:
```python
row_filter=EqualTo(('a.b',), 123)
row_filter=EqualTo(('a.b', 'c'), 123)
row_filter=EqualTo(('a', 'b', 'c'), 123)
```
