Paul, you're fit to prefer Arc over the rest because: 1) you're an experienced Lisper, and 2) it's your own creation, you know it inside and out and the language spec, manual, tutorial and research papers are somewhere between your ears (the most convenient type of bookshelf ;-)

However, it's IMO, unacceptable for a fairly new Lisp programmer to cast aside 50 years of Lisp research, development and deployment while brushing aside the industry's backbone languages, and herald Arc as the best thing ever when it isn't even finished.

I can accept personal choice and opinion, if kept to one's self and made in private. Even if someone sings Arc, or Clojure or Common Lisp or Scheme, praises, I am fine with it. But to say "Languages X, Y, Z suck because they don't allow me to write succinct programs", well, you're just trolling for X, Y and Z programmers to come out and straighten you out. The sort of macrology he is after (code-compacting type, not language extension) is pretty basic and could be done with the C pre-processor and M4. You can even write compact assembly programs with GASP, HLA, and NASM macros; it's not rocket science.

I reserve my judgment for Arc until it's done. There is no manual yet to hold the compiler accountable, and to save me from guess-work. However, what I can't ignore is blind fanboyism; if everybody here sang Arc praises, when it is just arc-tutorial.txt and arc.arc, and there were no "dissenting" honest voices, well, the place just wouldn't be the same.
