Coroutine scheduler for Python 3.5's await syntax
Asynker (IPA: /eɪˈsɪŋkɜːn/) is pretty much the least amount of code you need to use the “await” syntax. Typically packages like asyncio or curio implement two concepts at once: a scheduler and an event loop. The scheduler is a piece of code that decides what to run next and then runs it. The event loop is a piece of code that tells the scheduler what it can run.
Asynker only provides the scheduling part. This generally only makes sense if you are using something else as the event loop, e.g. something callback-based. Asynker allows you to use a callback-based system and easily convert it into a coroutine/await-based system.
The Future class used in Asynker is unrelated to any of the various Future classes found in the Python standard library (for now, anyway).

The API is like asyncio but different enough to probably introduce interesting behaviours for study in your code
If all you wanted was to use “await” in your code without loading 500 kB of code, then this is for you
