I answered as I did because the original question seems strangely broken. The premise upon which the question is asked is flawed.
What are goroutines, other than peculiarly broken coroutines? (Notwithstanding your point that go has a non-broken implementation of coroutines at experimental release stage).
It is true that Javascript has a goroutine-like facility for executing coroutines on a seperate thread. But there are languages (c++, c# at least) where coroutines can execute on separate threads without suffering from the broken-ness of goroutines.
