[New-bugs-announce] [issue24697] Add CoroutineReturn and CoroutineExit builtin exceptions for coroutines

[Yury Selivanov]

New submission from Yury Selivanov:

Since native coroutines (see PEP 492) hadn't had a separate type when the PEP was accepted, we didn't discuss that it might be necessary to introduce new exception types specifically for coroutines.

To maintain backwards compatibility with 3.5, I think we can do the following:

1. Add CoroutineReturn exception type, inherited from StopIteration;

2. Add CoroutineExit exception type, inherited from GeneratorExit.
