Also, I just noticed that the same user who has committed to the HN github has a port of Arc to be a Racket language: https://github.com/kogir/rarc-public . Do we know if he's a YC employee? Is this the next version of Arc?
"If you looked at it closely, I made many changes in the spirit of getting something running that PG (and you!) would likely not agree with."
I didn't see the repo while it was online, but I've always looked forward to Arc (or at least Anarki) becoming usable as a Racket language at some point, even if it were an awkward fit. Just how disagreeable are we talking, here? :)
