Any particular examples you have in mind? The demo is just referencing https://github.com/duckdb/duckdb/tree/main/extension/tpcds/d... which I wouldn't regard as a standard of good SQL; (implicit joins, yikes!) - but is a useful capability reference (as is tpc-ds in general).

As I tried to convey, I like SQL a lot - my frustration is more around the lifecycle and maintainability.

Happy to add more ergonomic references in other places, if you have some good examples to reference against?
