Of course, you could always go through the Python API, getting the sys module, extracting the relevant functions and calling them using the abstract API. That's what I'd recommend if this were purely a CPython question. But I assume that (for some reason) that's not appropriate for PyPy.

I had the same thought, but it actually only works cleanly for the "fetch" half of the equation. You'd have to muck around with actually raising an exception to handle setting those fields, which is really relying on implementation details). That said, it may be worth further exploring the idea of invoking appropriate snippets of Python code to get the desired effect.

My other question would be whether there's an existing private C API with the desired behaviour that could be made public, or if this would be a genuinely new addition to the API.

Cheers, Nick.
