Google Go `defer` ?

[yields]

I know the project hasn't reached that point yet, what do you think on Go's defer.

pretty cool, although I think most functions with lots of return statements could/should be separated, same with lots of branches

What instead about channels ?

[tj]

I definitely want first-class coroutines, so those would effectively be our channels but im not sure how Go specifics. I know they multiplex kernel threads, I'd prefer not to go down that road if we dont need to, personally I dont see the reasoning behind that when you can just spawn N processes and coroutines handle all the concurrency. Whereas with Go I imagine you'd just tell Go you want to consume N cpus, more or less the same thing with maybe a bit less memory usage
