String concatenation is particularly convenient after the + change for arc3.tar: http://arclanguage.org/item?id=9937. That's probably what I use + for most of the time.

I find thinking about whether or not I have to escape the "@" character is distracting

I find this is easier with proper syntax highlighting. My arc.vim ftplugin can detect if you have (declare 'atstrings t) and, if so, highlights the escaped parts of strings. That way, you know if @ is escaped just by glancing. But I don't mean to shamelessly plug, haha. I don't use atstrings either, but my reason is far lazier: in the middle of writing code, it's less effort to just use + than it is to declare then go back and start using @s.

What other goodies does your arc.vim plugin have? Is your editor at all integrated with the arc repl? Lack of a repl that I could easily send arc code to was the reason I switched to emacs after years of using vim. These days, using emacs with viper (vim emulation mode), I don't miss vim at all.

Sorry, I'm not going to be the one to write SLIME for Vim. :P I'm afraid the only "goodies" I have are highlighting-related. Off the top of my head:

- It can detect macros that take rest parameters named body, then highlight and indent them correctly.

- It uses R5RS's grammar & mz-specific extensions to highlight numbers correctly -- even weird ones, like

  #e1.5
  -nan.0+2.5i
  1/2@+inf.0
  #x8a
  #o1E+2
- It notices paren errors involving [], like

  [(+ a b])
- It highlights escape sequences in strings, like

  "\x61b \t c\u0064\n"
- It does its best to highlight ssyntax characters so they're easy to read.

You can check out more at http://arclanguage.org/item?id=10147 or http://bitbucket.org/fallintothis/arc-vim. It hasn't changed much since I first submitted it, though I've noticed it fails to highlight 0-argument function names like queue and new-fnid. Been meaning to fix that for awhile.
