[Python-ideas] async/await in Python

[Luciano Ramalho]

Yuri, thank you for writing PEP 492!

Victor Stinner reviewed the asyncio chapter in my book, Fluent Python
[1], and he saw how much I complained about the overloading of `def`
to define objects as different as functions, generators and
coroutines, and about `yield from` which doesn't say anything to me or
to many others to whom I've talked.

With `async def` and `await` you solve both these problems! Also,
`async with` and `async for` are brilliant. For the first time ever
coroutines will be real first class citizens in Python!

Alas, the book [1] is entering final production so it won't cover
Python 3.5, but I do hope to see what you propose in Python 3.5, and
if there is a second edition, it will be a pleasure to explain `async`
and `await`!

I did have time to add a paragraph about PEP 492 in a Further reading
section, citing your name as the author.

Cheers,

Luciano
