> typed databases let you express queries which are just super hard to express otherwise

Isn't type validation already in SQL with `CHECK` constraints? I don't see what the language is adding here exactly.

This sound very similar to https://www.geldata.com/ you might want to check it out.

This is cool, I have been working on something similar with Lean4 albiet focused on compiling to Substrait

This is pretty well done as well https://github.com/palladin/lean-linq

I belive we can do regular software much better using formal methods, and I want to better communicate the developing tools, learnings and methodology.

Would appreciate a quick reaction from the community.
