Is there something like `inspect_types ()` for numba '@ jitclass`?

Question

My numba @jitclassfails with TypingError and useless error message as soon as I try to create it: Can't infer type of variable '$0.1': list(undefined). Which variable corresponds $0.1(normally, perhaps the first one occurs, but in which function?). With normal functions, it inspect_types()will be very useful here. However, it does not seem to exist, either on jitclass, or on its methods. Is there something similar for jitclasses? I'm on numba 0.28.1 (currently the latest stable), but in general, I'm just interested in the latest version of numba.
