Explaining frames to my dad

    # currentframe() is needed only for getouterframes() to
    # have a reference where in the stack to start.
    # Meaning this is True: cfr ==  ofr[0][0]

    ofr = inspect.getouterframes(cfr)   # List[FrameInfo, FrameInfo]

    # FrameInfo has the following list-like structure:
    # [ class FrameType, str filename, int lineno, str function,
    #   List[str code_context], int index ]

    print(f'[frame]: i am func {ofr[0][3]}, born in line {ofr[0][2]}')
    print(f'[frame]: i got called by func {ofr[1][3]} from line {ofr[1][2]}')
