Thanks for the report. You can also solve this with getattr(hint, '__args__', None), or better yet, isinstance(getattr(hint, '__args__', None), Iterable).
This made me realise I've been careless about Python 3.6 hinting in general. Since v0.8, subscripting Internal or Hashed as objects (instead of string literals or from future import annotations) will raise a TypeError because __class_getitem__ is not recognised.
