How about asyncio in python 3 and gevent etc. in python 2?

[banachtarski]

Right I'm not saying that python 2/3 doesn't have these abstractions (to be honest I'm not an expert in either Python or Go, I'm a C++/Haskell guy). Just that the author is creating an obvious false dichotomy.

Callbacks (asyncio & gevent) are not the same as coroutines. You have to experience the callback hell to understand the difference.

[masklinn]

asyncio and gevent are coroutines, at least in all the senses that goroutines are.

In fact, so are regular post-PEP342 generators.

Asyncio does not use callbacks. It uses async/await syntax
