Seems to be here to stay, but I can't quite figure out why. The only thing I liked about it when I tried it out was the gotool, but it was hardly a reason for me to switch, given that I find the language itself kinda poor. Sure, it has cute syntax, but doesn't seem to provide much else that I couldn't do in another language, especially with contenders like Rust and Nim, or just plain old C, which is well-supported almost everywhere.

It's basically an unremarkable C-ish language with an advanced green threading library built in. Channels and green threads aren't that difficult to replicate, but select is.
