  Goroutines are probably closer to Fibers which D also has: https://en.wikipedia.org/wiki/Fiber_(computer_science) https://en.wikipedia.org/wiki/Fiber_(computer_science)

    They used to be closer to fibers years ago, when they were running on a single thread by default. Now they behave exactly like normal threads with the same problems. And fibers are threads anyway.

      Care to share a reference to them no longer being lightweight?
      • zzzcpan 8y ago
        They still start with tiny stacks, if that's what you are asking. I believe it's somewhere around 2 KB nowadays.

      goroutines are anything but threads. Here's a 40min talk explaining how Go's scheduler works: https://youtu.be/YHRO5WQGh0k https://youtu.be/YHRO5WQGh0k

        No, they are threads. It doesn't matter if they start with tiny growing stacks and whether blocking syscall wrappers call into the scheduler. Those are just implementation details.
