Have you by any chance seen the async keyword in C# 5.0? It allows one to write event-based code without callbacks obscuring the control flow. From what I've heard Python is in the process of copying this feature. Iced Coffescrip does something similar also.

This answer sums up my feelings best: http://stackoverflow.com/questions/7479276/what-is-the-main-difference-between-net-async-and-google-go-light-weight-thread http://stackoverflow.com/questions/7479276/what-is-the-main-... It's good for C#, but still a language wart that could be built-in. I like that Go only has one set of APIs for everything, not the sync way and the async way. It's sad that C#, which started out as a fixed-up Java, is now growing its own warts. Of course, Go's not perfect either.

  Very interesting. I haven't yet tried Go, but I don't see how it could match the performance of C# API with a single function. C#'s async methods offload any IO to the process IO completion port threads, thus freeing the current thread to do more work.

C#'s async methods offload any IO to the process IO completion port threads, thus freeing the current thread to do more work. Go generally uses synchronous functions, but a function in Go can be the subject of a "go" statement (sharing the name of the language should give an importance of how central this feature is), which causes the function to be executed as a goroutine (that is, asynchronously using an M:N threading model.)

    You meant to reply to test-it, but instead it looks like you're teaching a member of the Go team how Go works.

Node-fibers allows a similar thing with a pretty raw syntax. At least one clever programmer has painted over it and introduced await/defer in Node without any JS pre-processing [1]. If you enjoy CoffeeScript, Iced CoffeeScript does a great job of this too.
