A question appeared here about a simple mental model for PEP 550. It looks much clearer now, than in the first version, but I still would like to clarify: can one say that PEP 550 just provides more fine-grained version of threading.local(), that works not only per thread, but even per coroutine within the same thread?

Simple model:

  1. Values in the EC propagate down the call stack for both synchronous and asynchronous code.

  2. For regular functions/code EC works the same way as threading.local().
