I used Fable 5.1 and Opus 5.5 to build a Python interpreter in Rust. Appears to pass all the 3.12 code I throw at it.
To get a toy version that can run most things takes under 2 hrs. Half of that time is collecting the tests you want to pass, how it should evaluate the code, what your criteria are, etc.
