I'm liking Go's built-in, lightweight goroutine approach a lot more than the other "afterthought" approaches, but I think you need a runtime to dynamically allocate the goroutines and adapt flexibly. I don't want to write one myself or link to some library. If V doesn't have some goroutine equivalent (or better) built into the language, I probably won't be persuaded by its other features. Sending bits of code off to do their various jobs concurrently with (almost) the ease of calling functions sequentially would be hard to give up.
