The ABI breakage is not really a break, as the new field is inserted (almost) at the end, after any other fields used in C extensions.

self.write(f".co_name = {co_name},")
self.write(f".co_qualname = {co_qualname},")
self.write(f".co_linetable = {co_linetable},")
self.write("._co_linearray = NULL,")

Sorry, unrelated question, but does this mean I need to add the field from my _co_code change here too?

Technically, no. C will initialize any fields not explicitly mentioned to zero.
I think it is good practice to be explicit, though.

@markshannon I cannot push to the remote repo, could you please ensure the "allow pushes from maintainers checkbox is activated on the right column"?

There is no "allow pushes from maintainers" checkbox.
Could you make a PR on this branch?
