Problem: type annotations like dict can't be subscripted before py 3.9, even with from __future__ import annotations.
Solutions:
- Move from python native types to the
typing library types like typing.Dict
- Require python 3.9 (also means flows project needs to be upgraded to python 3.9).
- add compatibility for 3.8 using
typing library somehow without rewriting the entire codebase.
I prefer moving to py 3.9, will investigate that for flows. Also makes it easier to begin type hinting flows.
