Well, I guess using tabs for indentation is considered harmful. But if you
stick to tabs alone, and don't use spaces at all it could work. Of course,
some editors confuse tabs and spaces which brings a lot of trouble.
I usually convert all the tabs that were left out by editting the file

I don't follow such traditions. It is possible that lisp started before
languages with such indentation emerged (I believe it did) and people
still follow this tradition.

I'm aware that most editors support such a feature. However, I would also
like to _see_ what is going on in the program structure rather than being
"%"-happy. IMO, C-styling a Scheme code helps me understand where
everything starts and where everything ends. If I rely on using the
editors match-bracket feature, it would take me much more time.

Sometimes one has to work on terminals, for which the terminal program
or the editor does not support colours. I know joe does not, and this is
the editor I use on _terminals_ (on X I use gvim). What I mean is that it
is important for the code to be as readable as possible with or without
syntax-highlighting bracket matching or whatever.
BTW, I do add colours to my source code when publishing it on the web, by
using gvim. If you want to look at the results, check two of my lectures:
http://vipe.technion.ac.il/~shlomif/lecture/Lambda-Calculus/ - A lecture
about Scheme and Lambda Calculus (where I used C-style coding)
http://vipe.technion.ac.il/~shlomif/lecture/Perl/Newbies/ - A
double lecture about introducing Perl for Perl Newbies.

I don't have problem with people creating their own lisp variants, or
new languages in general. Nowadays there is an inflation of new languages,
and sometimes people use the most obscure ones for their projects.
I wonder how many languages can one human brain handle.

In that case, you can put each argument in a separate line, like this:
; Totally meaningless code
6 ; The placement
; etc. etc.
Of course, this is kind of a C style too, but I don't see any reason not
to adopt it.

But people will usually know which script they used to generate the image.
And after they have liked the script's results, they will want to create
an entirely different text.

I care for Windows users too, and I think we should have a working
Gimp-Perl for Windows. A prerequisite for it would be to have Perl/Gtk+
working on Win32, becuase Gimp-Perl depends on it. Maybe I'll get to
hacking all those things together one day.
In any case, I believe Tor Lilquivist can shed more light on the subject
of why Gimp-Perl for Win32 is not operational.

What do you mean by rules? And what do you mean by both: Python and Perl
or Python and Guile?
In any case, I once tried to create a Script-Fu script that will generate
text which it will extract from a text file, and failed miserably. That's
why I think Script-Fu is not enough for many practical reasons.

A more experienced programmer does not make less bugs. He just realizes
what went wrong more quickly.
