Thanks. Also nice. I like the explicit algorithmic approach.

Very nice. The Racket special sauce is the (match*...). I need to get my
head around what's going on there.

Thanks, that makes sense. However, I tried doing this with a variable
defined within a program, but it doesn't work. I would like the user to
define their our `root` function to wrap everything, however, when I try to
access it with `syntax-local-introduce` it isn't found. I have:

Hi David. You want to either look at the documentation of racket/system (to
open executables) or ffi/unsafe (for shared libraries with a C interface).

Hello. Is there a way to call to a C program from within racket? I'd like
to write a few Racket functions to call CGAL programs I made on C++. Thank
you.

As an example, this...
- a
- b c
- d e f
- g h
would get transformed into something like this...
'(a (b c) (d e f (g h)))
You can implement this in 2 stages. Stage 1 is line based parsing, turn
the input text into this list:
'((0 a)
(2 b c)
(2 d e f)
(4 g h)))

Maybe you found a bug in some of the Racket toplevel magic, in some
aspect of DrRacket, or in something else.
For a failure like this (and many others), one thing you can do is try
to prepare a minimal-ish test case that reproduces the failure. (This is
a real Racket source file, not an explan

No big deal, but I thought I'd report this:
I had a series of expressions that were generating unwanted output.
Putting them inside a (begin <>) did not work, for reasons that were
explained to me elsewhere (thanks!)
Anyway, I sorted the problem by enclosing every offending expression in
