These docs (https://arclanguage.github.io/ref/) are the ones I was talking about. I haven't read much, but there's no mention of parentheses anywhere. Also, there are symbols in circles to the left of concepts, e.g. F ! ? M, but no explanation of what they mean.
Generally, the docs seem rather terse to me; there's a lot of stuff that only makes sense now, after reading (http://aphyr.com/posts/301). "Clojure from the ground up" does start slowly, but by the end of Chapter 4, I really understood the idea of recursion and representing code as a tree, something that I don't think I could have got from the Arc docs.
That's fair. I think we worked on the reference because the tutorial seemed pretty good. Do you think we need something in between?
Edit: I thought the tutorial had come up in this thread, but it hasn't. I'm not used to having two questions from newcomers at once :) Are you aware of http://old.ycombinator.com/arc/tut.txt?
Ahh, I got a server error when I first tried to look at that; it seems to be working now, though. I've read the tutorial - it does seem pretty good. Thanks for the link :)
