I didn't know that Polars was implemented in Rust. In fact, it's very neat that Rust can interop with Python so cleanly, but that shouldn't be surprising since Python is basically a wrapper around C libraries.

But I still think it's surprising how much legs Python model of wrapping around C/C++/Rust libraries has. I would assume that if you have Python calling the libraries, you can't do lazy evaluation and thus you hit a wall such as Pandas.

But we seen with compiling Pytorch and Polars that you can have your cake and eat it too. Still have the ease of use of Python while having performance with enough engineering.
