[Python-Dev] PEP 492 quibble and request (original) (raw)

From the PEP:

Why not a future import

future imports are inconvenient and easy to forget to add.

That is a horrible rationale for not using an import. By that logic we should have everything in built-ins. ;)

Working example ...

The working example only uses async def and await, not async with nor async for nor aenter, etc., etc.

Could you put in a more complete example -- maybe a basic chat room with both server and client -- that demonstrated more of the new possibilities?

Having gone through the PEP again, I am still no closer to understanding what happens here:

data = await reader.read(8192)

What does the flow of control look like at the interpreter level?
