Go Concurrency Distilled

    The concurrency and threading in Go just feels like magic compared to every other language. I'm a goroutine addict and I refuse to be rehabilitated.

    Just from observations over the years, I don't think there's any other language quite like this, in terms of how things can end up happening in any thread.

      Doesn't that describe pretty much any green thread style concurrency implementation.

        No. Preemptive scheduling plus M:N mapping combination that Go has is not common in other major implementations.

        Other languages and their implementations of green threads usually have cooperative scheduling or M:1 mapping

          I'm curious; using hardware threads is M logical threads preemptively scheduled on N physical cores. In what way does this not satisfy the original criteria?
