Today O'Reilly updated the Early Release e-books of Fluent Python [1], adding chapters covering yield-from and asyncio.
[1] http://shop.oreilly.com/product/0636920032519.do Chapter 16 has a 12-page explanation about yield from and all 44 pages of chapter 18 are a friendly introduction to asyncio (at least as friendly as I could make it ;-). I'd like to thank Victor Stinner for kindly reviewing the yield-from and asyncio parts of the book, Paul Sokolovsky for the idea of his delegating-generator-pipe drawing, and everyone who's contributed to this project and this forum.
