Content
In CPython 3.7 it was possible to do: #include "pystate.h" ... PyThreadState ts = PyThreadState_Get(); PyInterpreterState interp = ts->interp; interp->eval_frame = my_frame_eval_func; This is no longer possible because in 3.8 the PyInterpreterState is opaque, so, Py_BUILD_CORE_MODULE needs to be defined defined and "internal/pycore_pystate.h" must be included to set PyInterpreterState.eval_frame. This works but isn't ideal -- maybe there could be a function to set PyInterpreterState.eval_frame?
