The idea behind Arc seems to be to create a new language to stand the test of time. The problem I'm having with this challenge, and Arc in general, is that it's very domain specific. Now, lisp /scheme is really great at making DSLs. This example makes me think that Arc isn't a new all-purpose language, but rather a DSL language that can easily be modified to withstand criticism. "It doesn't have feature x!!!" ...2 weeks later... "Well, it does now." I'm not saying that DSLs are insignificant, or that Arc's creation was trivial, but when examples like this are used, it feels more like a framework than a new paradigm. I think most Python/Ruby/Haskell/(modern language) hackers could fairly easily implement a library to do what Arc does in about as many lines, but they wouldn't call it a new language.
