Arc and innovation
Some blogs and mailing lists are full of a discussion about the innovations in Arc. One partial consensus seems to be ‘to little, to late’ at least for an magnum opus. If you want to see an firework of innovation in programming languages, take a look at Wouter van Oortmerssens programming language page. You absolutely must see the visual programming examples and all the other ideas which question the fundamentals of programming language understanding. Pure genius.
