A lot of people are super productive with Go, despite all the detractors criticizing the (supposed) lack of people's favourite language features. That's reason enough to have a closer look. Conceptual purity doesn't buy you anything in the real world.

Try it on a small project and decide for yourself.

There are a lot of detractors repeating the same thing: "It does not have all the features of my favorite language X so its bad", while not explaining why they don't just use X.

Just try it out for a project or two if you're curious.

This is actually why I'm posting this, both Nim and Rust are higher on my languages-to-try list. Free time is sadly not unlimited and I'd like other people's opinions as well :)
