Hello, In Modules/main.c, wherever PyImport_ImportModule() is use, the variables (runpy and sys) are named as follows: runpy = PyImport_ImportModule("runpy"); // line 265 sys = PyImport_ImportModule("sys"); // line 444 Can we also rename 'mod' to 'readline' for consistency in line 215? PyObject *mod = PyImport_ImportModule("readline"); // line 215 if (mod == NULL) { PyErr_Clear(); } else { Py_DECREF(mod); } Suggested changes: PyObject *readline = PyImport_ImportModule("readline"); if (readline == NULL) { PyErr_Clear(); } else { Py_DECREF(readline); } Let me know your thoughts. New guy here, Gerol
