It is a pong clone including the ability to control it using knobs
like the original.

Hi: I've recently discovered Clojure and have loosely followed some
of the discussions here. First of all, I think Clojure is a great
language, since I also love Lisp, and I feel that the Java platform is
the most robust for web development. But I perhaps come from a
background a little differen

You get Erlang, and you also get s-expressions and macros.
Common Lisp and Scheme are the obvious choices, I suppose.
Learning common lisp I would probably go towards clozure common lisp,
or clisp.

This question is tricky to answer, do to the way things are bound in
Clojure.
It is possible to get the name of a the symbol the fn is bound to, but
the fn object itself has no name. Also, fn objects can't take
metadata (but this is supposed to be fixed eventually), so what you

Suppose we define a function called sq:

(do (println "sq")
(* x x)))
I wanted sq to print it's own name when run; to make it do so I
inserted the name as a string.
Is there some way to dynamically determine the name and so avoid using
the string?
Similarly, is it possible

That's a concise and clear way to summarize the issue.

support required to write syntactically correct Clojure code is pretty

One wrinkle here is that in Clojure "," is whitespace. It would be nice not to

I may be way off here and if I am feel free to flame!
isn't it true that lisp being an AST transfers the overhead of parsing to
humans ?

i.e. parsing the language to AST ?
