I did ponder whether to not mention Go in the title, but I had noticed that it's unclear what the devs mean by "support for 23 languages". Go is known to have been their main focus. In general, there is no documentation whatsoever, although the editor is interesting.

We did start off with just Go. After doing a bunch of infrastructural work, we added another, Ruby. We've just finished generalizing this, in a way that both more 1st- and 3rd-party extensions can be created. To date though, we've only gotten to Rust and Swift.
