A lisp newbie example app.

[Asbjørn Bjørnstad]

With little to do over the holiday period, I wrote up the process of
writing a trivial little game. And I do mean trivial.
If you got nothing better to do either, you can find it here:

Very nice write-up. This is a nice contrib. Makes me think it is better
for newbies to learn from each other than from us dinosaurs.

Very nice and "clean". I did not look carefullly at the code yet - it
take some times for a "yet another newbie" like me, but i appreciate
it.

One slight nitpick - consider replacing (:add-use-defaults t) with
(:use :common-lisp) in the portable (non-CAPI) section -
:add-use-defaults seems to be a Lispworks-specific thing marring what
is otherwise perfectly portable code.

Agreed, and done.

Another one:
Write

(defun print-grid (grid)
(format t "~{~{ ~a~}~%~}~%" (loop for i on grid by 'cdddr
collect (list (first i) (second
i) (third i)))))

instead of

(defun print-grid (grid)
(format t "~{~{ ~a~}~%~}~%" (loop for i on currentpos by 'cdddr
collect (list (first i) (second
i) (third i)))))

and perhaps (logxor p m) instead of (mod (+ p m) 2) in apply-move

Ciao, Fred

A bug! And I thought I'd tested everything so thoroughly.

Maybe next time.

Thanks to all the nice feedback, I got encouraged to write another piece,
so if you want me to stop, you now know how. :-)

This time I didn't write a program, I just tried to give an impression
of how I (ab)use the REPL.

Warning: my way of using the REPL could seriously offend your sense of
estetics. Ugly code has a main part in this episode:
