Currently typing functions get_origin(), get_args() and get_type_hints() do not support GenericAlias.
>>> from typing import *
>>> get_origin(List[int])
<class 'list'>
>>> get_origin(list[int])
>>> get_args(List[int])
(<class 'int'>,)
>>> get_args(list[int])
()
>>> def foo(x: List[ForwardRef('X')], y: list[ForwardRef('X')]) -> None: ...
...
>>> class X: ...
...
>>> get_type_hints(foo)
{'x': typing.List[__main__.X], 'y': list[ForwardRef('X')], 'return': <class 'NoneType'>}
