asyncio

When Guido van Rossum started to work on adding async features in Python 3, part of the community pushed for a Gevent-like solution, because it made a lot of sense to write applications in a synchronous, sequential fashion rather than having to add explicit callbacks like in Tornado or Twisted.

But Guido picked the explicit technique, and experimented in a project called Tulip inspired by Twisted. Eventually, the asyncio module was born out of that side project and added into Python.

In hindsight, implementing an explicit event loop mechanism in Python instead of going the Gevent way makes a lot of sense. The way the Python core developers coded asyncio, and how they elegantly extended the language with the async and await keywords ...
