I definitely had plenty of complaints (there's no way in the language to detect when a process exits, for example -- though you can at least build one yourself)

I definitely had plenty of complaints (there's no way in the language to detect when a process exits, for example -- though you can at least build one yourself). I don't think LtU approval is necessary to have done something good. We need more tools that help programmers solve problems of concurrency without losing their feet. Tools that aren't entirely groundbreaking are very useful here, because you can take a guy who knows only c++ and have him write a bit of go. I can't as easily get him to use twisted or erlang or even node.js.
