Thanks for putting this together!

Bit of feedback around tests, and the general approach looks good.

Thanks for the review @cpcloud ! I think I found a fragility with how we generate argument names for the lambdas in SQL. Waiting to here your suggestions on how to fix that, I'm not familiar with the reasoning behind how to generate those arg names. Can we just do __ibis_param__, not templating in the name of the arg?

I think I found a fragility with how we generate argument names for the lambdas in SQL.

Certainly possible!

We're generating names to workaround an issue in DuckDB (opened by you in #7676 😄, fixed in #7741).

I reported this upstream here: duckdb/duckdb#9981

and the fixed was merged 3 weeks ago in duckdb/duckdb#10150.

I think DuckDB is the only backend that had this problem, so when DuckDB releases a format-stable version we can bump its version lower bound and remove the workaround.
