My concerns with the behavior of `__origin__` possibly changing in the future seem to valid. In Python 3.5 and 3.6 the behavior is 

    List.__origin__ is None
    List[int].__origin__ is List

while in Python 3.7

    List.__origin is list
    List[int].__origin__ is list

Is it likely that this is going to change again or can I rely on the current behavior with Python 3.7+?
