Would this mean that with this PEP I can write a for loop like this?
for (await?) item in async_generator():
... code
Or am I misunderstanding something?
No, this is an illegal syntax and will stay that way.
The PEP allows to do this:
[await item for item in generator()]
and this:
[await item async for item in async_generator()]
The idea is to remove any kind of restrictions that we currently have on
async/await. A lot of people just assume that PEP 530 is already
implemented in 3.5.
