Just a quick heads up that the AFIO review is postponed till Monday to give me more time to refactor the docs to match the final API. Some quick notes on what will be presented for review, so there are no surprises: 1. I won't have the time to rewrite the code examples into C++ 1z coroutines before the review unfortunately, so you'll get a warning sign in the docs saying that is coming. The code example this matters most to is the find regex in files example as the code is very messy (full of callback handlers) without coroutines. 2. The API presented is expected to be a final API, but the implementation will be a messy conglomeration of the existing mature dispatch engine with the new lightweight future-promises. In other words, code will compile and run, but the internal engine is going to be completely replaced eventually as I debug lightweight future-promises. As lightweight future-promises is all brand new code mostly written between 12am and 4am each night since May after a work day, I don't hugely trust it enough to present you guys with an engine based on it. Just because it passes a conformance suite doesn't mean it is without quirks - plus, I discovered some surprises in the Concurrency TS about which I'll need to get some clarifications. As I mentioned though, the user facing API will be final, as promised. And it does use monads and lightweight future-promise. 3. Minimum compilers will unfortunately be GCC 4.8, clang 3.2 and VS2015. Sorry about that, lightweight monadic future-promises substantially bumped the compiler requirements, even as it is I have several GCC 4.8 specific workarounds.
