These are needed when creating function-like (et al) objects from extension module code, not just for runtime frames. And then explicitly define which code object fields are expected to always be populated and which are expected to be None on emulated code objects that don't contain Python byte code? (e.g. some fields should be zero or the empty tuple, rather than being set to None) Cheers, Nick. >
