Re: The differences between lua coroutine and golang goroutine?

[Mateusz Czaplinski <czapkofan@...>]

At a risk of repeating what previous posters wrote (I'm sorry, it's
too early in the morning for me to understand "less 'no
non-preemptive' guarantees" :P), from what I know:
goroutines are partially similar to coroutines, especially in that
they tend to veer on the "cooperative" side of the fence (e.g. an
empty loop is uncooperative); however, they can be executed in
parallel over a pool of threads (where the count of threads is
~implementation-defined, but see also GOMAXPROCS). And it's true that
"there are some clear points of control transfer" (although
personally, I didn't yet care enough to investigate if they are really
so clearly defined in the spec) - meaning that at these points a
goroutine can be paused and some other one chosen to execute on a
particular thread.

Hope this helps should you still have some doubts.

Regarding channels, I'm not sure what would you like to know. I think
their basic ideas are already described pretty extensively on
golang.org in all the tutorials and faqs.
