Thanks for your explanation.
I think we can add support for lambda expressions in CTE syntax later, for
example:
```
with f as (x, y) -> x + y
select f(c1, c2) from t;
```
Another thing, I provided the wrong PR link, and the correct one should be:

Hi folks,
Does anyone know if Calcite supports parsing lambda expressions? (Or can be
extended easily to do this)
I.e. something similar to Teradata Presto:
https://teradata.github.io/presto/docs/0.167-t/functions/lambda.html
