> Note that PyCode_New() is not the only change in 3.8 beta1 that breaks Cython generated code. The renaming of "tp_print" to "tp_vectorcall" is equally disruptive, because Cython has (or had) a work-around for CPython (mis-)behaviour that reset the field explicitly to NULL after calling PyType_Ready(), which could set it arbitrarily without good reason. Can someone please open a separated issue to discuss tp_print backward incompatible change? This issue is about PyCode_New().
