> Even on that aspect, I'd be interested in knowing how you'd achieve bidirectional communication async generators. How would the ASGI server call into the application and handle messages coming both ways? Surely, it can't just `async for message in agen: ...`, as that would only replicate the `send()` ASGI callback — what about `receive()`?
Yield is two-way. ``result = await agen.asend(next_message)` ` et al.

Having worked with Python async for 3 years, anything that asyncio touches is completely poisoned. ASGI is another in the line of terribleness of the modern async ecosystem.

A second async generator.

Require an async generator. Done!

Much like asyncio, something isn't good just because it's being pushed.
There's the problem. WSGI is fundamentally flawed too - it could also be using generators for a two-way communication channel instead of stringly typed callbacks.
In a world where Python has optional static type hints, it would be nice to have concrete objects passed too.
It's convuluted, it's not structured concurrency (https://vorpus.org/blog/notes-on-structured-concurrency-or-g...), fundamentally despite being async/await a lot of networking code is based on callbacks anyway (see: asyncio.Protocol), and I've had a lot of trouble debugging code that spawn tasks because asyncio code has zero obligation to care about any of the tasks it spawns.
> Django 3.0 begins our journey to making Django fully async-capable by providing support for running as an ASGI application.
Bleh. ASGI is probably the worst implementation I can think of for a common async interface. Stringly-typed callbacks? async generators exist for a good reason. It's also very asyncio-centric, and asyncio is Not Good.
I've lost a small amount of weight whilst still entirely eating bread this year. The only thing food groups have to do with it is how filling everything is

My body also doeesn't obey the laws of thermodynamics and manages to gain an extra 1200kcal a day out of nowhere because I eat bread
