I have reviewed. It looks good, and I’m sure we can get this in before 1.37.
Let’s discuss further on the PR and in

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:

Thank you. I’ll take a look.
For what it's worth, I take issue the people (not you - they are in Spark

functions’ or ‘function values’. The lambdas can only be used within that
particular function call, not passed
Hi devs,
I have opened a PR regarding lambda expressions, Calcite will support
lambda expressions like `(a, b) - > a+ b` in function parameters if this PR
is merged.
This PR includes the following:
- Parse, validation, SqlToRel and RelToSql for lambda expressions.
- Execution of higher-order
