Red is one of those languages that I forget about until a story like this comes along, and then I'm reminded how much I want it to mature to 1.0. Looks like full I/O support will be probably be released in the next 12 months or so, which will really open up some interesting opportunities. (The Rx capabilities in the current version mean that the only thing holding me back from using it in a professional capacity is the lack of an OSX GUI backend.)
