For all you dear academic Racket scribomans, here's a lesson from Mark Tarver,
the ingenious inventor of a new lisp-like language, Shen (more on that
beautiful language can be found here: http://http://shenlanguage.org). In his
article "Why I am Not a Professor", this clever man says the fol
Dear Racketeers,
Wishing you a very happy and prosperous new year!
Let the new year bring us much more good documentation for web development in
Racket. And much less artificial academic articles, far away from practice.
Cheers!

I don't feel any need in my heart and brain to write "examples" for such a
poorly undocumented piece of code like Racket Web Development library.To

No, you are not dumb. It's only that Racket web documentation sucks. But never

Of course I care!
I love racket and deeply respect all of you. But, I'm afraid that if you go
this way, Racket remain just another never used "academic" language.

Jordan, beautiful are your ideas and suggestions, but unfortunately, I think
that they are futile. Why do I say this? I think that Racket primarily serves
to a specific group of people as an inexhaustible source for mass-production of
always the same academic articles, and much less for everyda
think this is one of the main reasons for poor use of Racket in the web
(otherwise, Racket is just great!).

Here http://www.ccs.neu.edu/home/matthias/HtDP2e/i2-3.html i found this:"You
can use the function show-in-browser from "2htdp/web-io.rkt" to display the
result of functions such as my-first-web-page in a web browser". Unfortunately,
I cannot find web-io.rkt nowhere in Racket, version 5.1.3.

You can't compute (car (1 2 3)) because before car even begin, it's parameter,
list (1 2 3) must be evaluated, but 1 is not a procedure name. It is different
than in (quote (1 2 3)) where such evaluation doesn't take place. > Date: Sun,

Sorry Shriram, i didn't mean to insult you or anyone else, but my poor english

Saying that (quote (1 2 3)) evaluates to (quote (1 2 3)) [instead to (1 2 3)]
is the same nonsanse to me like saying that (+ 1 2) evaluates to (+ 1 2)
[instead to 3].

Wait a minute, I dont get it! You are saying that (quote (1 2 3)) evaluates to
(quote (1 2
In Common Lisp or Clojure REPL, expression '(1 2 3) evaluates to (1 2 3).
But in #lang racket the same expression evaluates to '(1 2 3). Why?

I'll take a look at Dybvig's article. And, i hope that upcoming book, "Realm of

By the way, when will "RoR" be published? I'm so eager to see it! :)

It seems to me that macro process-state is not expanding at all.
