Has anyone here ever played with Golang? What's people's opinions with it? It looks quite interesting at first glance; kind of like a cleaned up C++. I was going to look at Node for web development but it seems to me that Go's Goroutines are a lot more intrinsically attractive than the various workarounds for callback hell in server-side JavaScript (promises etc.)
I was going to have a play with Scala over the holidays but maybe Go might be more interesting.
