Sorry I should have been clearer. I can get to an arc repl just fine. Say I wanted to use arc programs from the shell:

$ cat somefile | somearcprogram

How would I get that working?

Cool. It looks like they pulled some of your patch into anarki, so maybe I should take a look at it.

I think this is right.

  arc> (def quadratic (a b c)
             (= minus-b (- 0 b))
             (= radical (sqrt (- (* b b) (* 4 a c))))
             (= divisor (* 2 a))
             (= root1 (/ (+ minus-b radical) divisor))
             (= root2 (/ (- minus-b radical) divisor))
             (cons root1 root2))

For what it's worth I'm trying it out on v360 because thats what I happened to have installed, and so far no problems. Although I haven't really done much. If I run into anything I will post.

I went through some of the examples in the tutorial with v360, but when I tried the hello web app, it failed. Not sure if it's due to v360, or not. I guess I can uninstall it and install v352 :(

"... blog.arc seems to work with v360. :) ..."

Same here on a ubuntu 7.10 gutsy 64amd. There's no (easy) way to do an install for v352 w/o doing a source compile (works) and manually installing the files (can't be stuffed).
