That's a bit of a slippery slope, though, isn't it? I'm already doing everything I want to do with Go, so all of the things it's "missing" don't really matter to me. If we had to learn and switch languages every time something implemented a feature the other did not have, we'd be refactoring our code every other week, wouldn't we? That's not to say those other languages don't interest me, or that I would eschew learning for the sake of learning. I've been eyeballing Rust for a while, and I do think it may someday fill the role Go currently fills for me, but for the type of coding I currently do Go is more than sufficient.
