[issue37250] C files generated by Cython set tp_print to 0: PyTypeObject.tp_print removed

[Jeroen Demeyer]

Jeroen Demeyer <J.Demeyer at UGent.be> added the comment:

I would argue for the pragmatic solution: PR 14193 fixes that old Cython-generated code. More generally, it fixes API compatibility and doesn't make ABI compatibility worse than the status quo (the proposal of putting back tp_print in place of tp_vectorcall_offset does).

Of course, it may not fix every single use case, but even if we can't fix that hypothetical 0.1%, we can still fix the 99.9%.

The proposed fix is very small and only applied to 3.8, so there is no long-term maintenance burden. So the obvious question: why not? What's wrong with PR 14193?
