Philip, you're right, a DSL doesn't have to mean a restricted language
(like BSL). I completely missed that point in my last response to this
thread. For some reason BSL got in my head and I incorrectly equated that
concept with the embedded DSL approach suggested by Matthias as I was
writing my re

Have you considered the development of a railroad-simulation language within
Racket that fits your domain? If you can provide peopl
I don't know where you are going with your book, but are you sure forcing
people to use the command-line interface is a good idea? Racket can be
fully used through the GUI (even managing packages can be done through
DrRacket). I agree with explaining both DrRacket and raco, but why can't

Lots of good advice and opinions here. Thanks everyone. I'll try to respond
to all of them in some way ...
1. @David K. Storrs and @Eric Eide: Renaming the folder. This works for
sure but _my_ preference is to use a symlink (as Eric also mentioned) as it
doesn't touch the original folder layout
Take at look at Racket's `for' loops. They are very flexible.

Hi, everyone.
I want to write loops simpler.

In Common Lisp, I like the extended loop like "for" of C-language.

Thanks for your advice, Alex. I'll be used to require point-free package.
