Yes, Red is another fine language. However, to be fair, I would say Red is practically like Rebol v3. Arturo's goal is not to become yet another Rebol, but combine its positive aspects (which are a lot) with other features of modern programming languages, mostly functional programming -oriented. Actually, Arturo's influences range from Rebol to Ruby, Haskell, Tcl and even Forth or Factor or... Swift.
In any case, I'm all ears for feedback/ideas/suggestions. Code contributions are more than welcome as well - it's been just a one-guy thing so far, and I can honestly not find time for everything :)
