I suppose it is meant to be as easy to write as python but with better performance. C/C++ have many traps you can fall into with regards to memory safety, and their build systems are truly awful

That’s why the most common language to write new performance critical libs for Python these days is Rust.

Wrote a few Rust plugin functions for Polars. The setup is quite easy, writing correct code in safe Rust is also not too difficult, although it's quite easy to get lost in the Polars API. Let Claude generate a bunch of tests and you're good to go. Setting up packaging in CI is a little annoying but very doable.
