My subsequent comment acknowledges that JIT means more than compilation at runtime. In .NET desktop, it means compilation of all CIL to native on every run, just before execution. To me, that's just executing the second pass of a compiler at launch time, but Anders Hejlsberg says it's JIT[1], and I'm not going to argue :)

Anyway, I've made a follow-up post that shows how to JIT compile a subset of Python, directly based on the previous techniques: https://csl.name/post/python-compiler/
