Scheme MiniLab
The Scheme minilab gives you an opportunity to explore one of two things about the Scheme programming language.
Macros: Using syntax-rules, you will implement several simple macros. As has been mentioned before, the language CFWAE is remarkably similar to Scheme. That being the case, you can actually write macros to implement if0, with, and fun. This will allow you to then program in CFWAE without having to run your interpreter. A little double-bonus extra effort is required to implement FEARCOW in macros, but it can be done.
System Scripting: If you’re not interested in exploring the world of metaprogramming, you could instead explore some of PLT Scheme’s features that make shell scripting pretty easy.
Either way, the hope is that you can carry out these explorations in roughly 45 minutes. Enjoy.
