This questions was raised yet in comments to Kickstarter campaign, and I'd like to set up this ticket for informal background discussion, to allow interested parties to further discuss/share ideas on this matter, and serve as guide for further implementation directions.

Summary of my proposal: Choose asynchronous concurrency via generators, as native, Pythonic, high-level way to do concurrency in Python.

I guess almost everyone heard that Python generators can be used to implement coroutines, and possibly few actually use them and up to date with their status. Myself neither, so I was taking last couple of weeks to survey state of the art in Python async concurrency in general, and generators in particular. There appear to be gradual advances since 2.5, and process continues, with upcoming 3.4 offering standardized async coroutine framework.
