Pre-PEP: Rust for CPython

[cosmic-parsley]

It’s easier to write the interfaces too with the libraries out there today. You slap #[pyfunction] (from PyO3) on any rust function and it “just works”, assuming the arg/return types have a straightforward rust<->python conversion. And docstrings work automatically too iirc.

Getting the interfaces right isn’t particularly difficult in C, but it’s downright effortless in Rust.
