I agree with a lot of this. I'm especially looking forward how generics should make it easier to build a library of high level concurrency patterns that people can use in Go, instead of everyone trying to build their own. Promises (which would allow you to start a number of parallel tasks, then wait on the results), "parallel for" with controlled amounts of concurrency, etc. The M:N scheduler is great, and the ability to easily spin off Goroutines is really nice, but I think most people shouldn't need to manually launch goroutines most of the time. Goroutines should just be an implementation detail.
