Actually, we currently inline the straight C code for this in CPython for performance reasons, so, no, going through Python code isn't going to be a good idea. > 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. I'm not aware of any. The code in CPython (especially in ceval.c) always uses direct field access.
