I really enjoyed watching this talk about how Go has added preemption to their coroutines to avoid stop-the-world GC latency caused by long-running tight-loops in tasks:
GopherCon 2020: Austin Clements - Pardon the Interruption: Loop Preemption in Go 1.14
Very interesting and inspiring to see how far they’re able to push this concurrency model! Interesting to see where they’ve been and what they’ve done and imagine how it might or might not relate to julia’s future in this area.
