[issue41756] Do not always use exceptions to return result from coroutine

[Serhiy Storchaka]

Serhiy Storchaka <storchaka+cpython at gmail.com> added the comment:

There are other abstract object APIs: PyNumber, PySequence, PyMapping, etc. In particularly PyIter_Next() works with the iterator protocol, there is no single iterator class. Seems PyGen_* API is related to concrete class, but we can introduce new namespace for the generator protocol.
