car -> first
cdr -> next

So you really can compose the names. They're still less concise, but only by a couple of characters. If you really wanted to save those characters, use fst/rst (and ffst, frst, etc).
EDIT: I failed to completely read your post; it seems you already mentioned ffst etc. Don't know that my comment adds much to the debate.
Actually, those were new to me -- I was trying to use fst and rst, and failing at it. While the Clojure way works better than my example, there's something about it that I don't like. Maybe it's simply that it's new -- if that was the original way, I'd react similarly to introducing car and cdr.
Just for your information, there is a "flag" button on the "X points by Y" line, which can be used to mark spam messages. (Or at least there is if you have over some amount of karma.)
That's way too funny. I saw this a while back and thought 'flag' was to bookmark the post as 'important'.... so naturally was 'flagging' some of pgs' posts. I'm glad it didn't end up marking his posts as spam!
It does most of what you describe (connecting/disconnecting from a running Arc repl). I don't know if you can use it to save cron jobs, but that's not something I typically need to do.
Yes, I use screen very heavily, and I do use it to leave an arc process running, and connect to it again later.
But it can't connect to an arc repl that was executed by a non-interactive shell, such as via cron or initd. That's what I use the pipe system for, and a similar system could easily be used by an ide to communicate with arc and not create a visible shell window.
No I haven't. I've been meaning to look into that, but so far I've just been using arc.el. If you know anything about getting arc to work with slime, and have any success in that area, I'd be interested.
i actually use Vim which is more than sufficient for my needs. what i'm thinking of making is a completely noob-oriented IDE, one where ideally the user does not even have to know about mzscheme this or arc3.tar that
Another use for symbol macros is in writing package/module systems, where you want to determine which package a symbol goes into based on the compilation context.
You can do this to a certain extent already, using package!symbol notation, but this still doesn't allow using symbols without prefixes.
Another option is the Anarki stable branch (http://github.com/nex3/arc/commits/stable/), which has most of fixes necessary to make most of Arc work portably on Windows and other OSes. (And, being a bug-fix branch, the amount of other random material is limited.)
I agree with the option, but I also think these posts will fall off the deep end in about 2 months. By then new members may only discover the option after they've discovered the problem. So we're not really saving new members wasted efforts unless the install page guides people.
pg: Even if you'd rather not think about supporting Windows portability yourself, providing a link to the Anarki stable branch would help new Windows users. Finding this stuff on the forum after it's fallen off the top couple of pages is not very easy.
