Another common use case is dependency injection / IoC: - Injector (https://github.com/alecthomas/injector <https://github.com/alecthomas/injector>): - Flask-Injector (ok it's the same underlying injector):
Pretty cool! This is already using get_type_hints() so it's perfectly compatible with PEP 563:
https://github.com/alecthomas/injector/blob/master/injector.py#L915
- Apistar components (https://github.com/encode/apistar#components <https://github.com/encode/apistar#components> ):
This is using inspect directly so will have to migrate to get_type_hints() later. But, as the PEP mentions, it should already be using get_type_hints() since people are free to use forward references even today.
Thanks for flagging those use cases!
