> What's the alternative with Gevent? Passing callbacks everywhere? You build on callbacks to create futures and queues. That’s how you do async programming in any framework. AsyncIO works on top of this and so does Gevent. The only real difference between the two is that asyncio explicitly types functions that do IO. The fundamental advantage is little more than a typing decorator. The reason that JavaScript was such a crapshoot of callbacks was because the majority of JavaScript developers had no idea what a future/promise was.
