Hi Yury,

just for my understanding:

We propose to allow the use of ``await`` expressions in both
asynchronous and synchronous comprehensions::

    result = [await fun() for fun in funcs]
    result = {await fun() for fun in funcs}
    result = {fun: await fun() for fun in funcs}


This will produce normal lists, sets and dicts, right?

Right.

Whereas the following will produce some sort of async lists, sets, and dicts?

    result = [await fun() async for fun in funcs]
    result = {await fun() async for fun in funcs}
    result = {fun: await fun() async for fun in funcs}

If so, how do I read values from an async list/set/dict?

Consider "funcs" to be an asynchronous generator/iterable that produces a sequence of awaitables. The above comprehensions will await on each awaitable in funcs, producing regular list, set, and dict.

I doubt that anybody ever would write something like that; this is just examples of what the PEP will enable.

There is no concept of asynchronous datastructures in Python.

Thanks,
Yury
