One neat thing that I've written in guile, as part of a larger C++
application, is a recursive decent parser. Thanks to a nifty macro or
two, the syntax description maps almost directly to scheme code, which
kind of highlights what you can do with Scheme that is very difficult
in other languages: create a mini-language in the problem domain, and
then solve the problem using the mini-language.
Doing the same thing in yacc/lex would have been horrible to code, and
horrible to maintain.
Maybe this is too much for an introduction...
