Yes I'm still using Python 3.12.0rc1, good catch! Will upgrade 🙂

I eventually made use of pysource_minimize, thank you again for showing me how to use it 🙂

The SystemErrors seem to come from pysource_codegen itself:

We will ignore them for now.

Erm, it looks like I can't regenerate the same code when debugging through VSCode... 😮‍💨

Oh, OK, it actually depended on the Python version used.

Yes, it depends on the python version. Are you still using a 3.12 pre-release? This errors looking familiar to me. python/cpython#109219

I put an quick implementation together based on your tweet which finds some errors #216.
the pysource-minimize part is the important part here which gives you this nice small source codes.

Let me know how you want to integrate it.
You can also take it from here if you want.
