[breakingcups]

I can't say anything about Scala since I haven't played with it, but I like Go a lot. It has a lot of thought put into it to make it a practical language, not a interesting research language. This might seem boring at first, but I find it keeps being rewarding when you use it. The concurrency features baked into the language are also top-notch. They made me like writing concurrent code as opposed to dreading it.

Can I ask what language(s) you already know, if any?
