I'm not sure that's true. Some people weren't happy about the PEP. Few people are using it in any case, so most are either still unaware of it or haven't used it yet themselves.
I'm very excited to start using it. It will be the thing that finally pushes me to Python 3.
>Few people are using it in any case
Probably true, but it's only been out for 2 months now, and most people who needed this feature are either using an ugly workaround (guilty) or have moved on to other languages that already had this feature. This time, I'm glad Python joined the crowd.
Yeah. I've played around with asyncio and aiohttp in python 3.5 for a crawler and loved it. But then I ran into dependency hell down the line manipulating the data, so that was that (for now).
