not linking python: ```shell (venv) ~/python/out $ nm nuitka_test.cpython-39.so -gD U PyArg_ParseTuple U PyArg_ParseTupleAndKeywords U PyArg_UnpackTuple U PyAsyncGen_Type U PyBaseObject_Type U PyBool_Type U PyBuffer_Release U PyByteArray_FromObject U PyByteArray_FromStringAndSize U PyByteArray_Type...
