C++ Coroutines come naked. Just the language feature, no library support apart from a few traits that allow developing coroutine adaptors.
In this session we will start with just a compiler that implements a coroutine TS and a reference networking TS implementation and through (mostly) live coding together we will develop a cool, efficient and beautiful async networking app.

Ok, now i need to wait for Scott Meyers to write a book about it and explaining it in length and with deep technical understanding.

But it is the case that every future *must* run on a thread separate from the main thread, no? Otherwise it would be the case that, in the networking example for instance, the first read is scheduled inside the async_accept completion handler, but the co_await would immediately block that stack and it could never return back to the networking event loop, so the read operation would never be executed, leading to a deadlock. Correct?

Coroutines TS implements stackless coroutines, where suspension only affects the current function and does not block the stack. There were Coroutine presentation in other years at CppCon that went into the details. For example: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-_fu0gx-xseY.html gives some background info. This one ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-8C8NnE1Dg4A.html goes over implementation details.
