Nobody says asyncio is not well designed if that is what you were 
thinking about others who have issues with asyncio were thinking (did 
that make sense?).

That is exactly what people complain about. They don't like this 
thinking. They don't like this "all in or nothing" attitude.

You may ask why? Because people want to try stuff out. But when in order 
to do so, they need to convert 10 mio lines of code in order to *see 
some results*, it just looks insane to them (looking at you, too, Python 3).


The point is not to have some toy projects show-casting the abilities of 
asyncio, but trying it out among the lines of formerly 100% synchronous 
code.


I am sorry but that is the world we live in, so, we need to compromise; 
otherwise people will disagree and not follow. This is not about doing 
100% right and perfect design but taking people with you on the journey.


Best,
Sven
