Naked coroutines live (with networking)
summary
Shows how C++ Coroutines TS plus the Networking TS can be used to build an async TCP server by live-coding two approaches: an easy adapter that uses std/boost::future (drops throughput by ~40–45% versus the original 75 MB/s server) and a hard approach that implements zero-overhead awaitables for async_read_some/async_write (restores native 75 MB/s and beats a future-based reposting microbenchmark by ~10x). Also covers cancellation via handler-destructors, allocator placement to avoid heap churn, and a proposed symmetric transfer to guarantee tail-call resumptions.
