## Can you summarize the differences between your made-up language and Scheme, OCaml, and Haskell? ##
The made-up language we wet our toes in in week 1 is called Kapulet. (I'll tell you [the story behind its name](/images/randj.jpg) sometime.) The purpose of starting with this language is that it represents something of a center of gravity between Scheme, OCaml, and Haskell, and also lacks many of their idiosyncratic warts. One downside is that it's not yet implemented in a form that you can run on your computers. So for now, if you want to try out your code on a real mechanical evaluator, you'll need to use one of the other languages.
