Hi, I’m back. I’ve finally sorted out the guidelines for blogging in Credit Suisse.

Here is something I have been playing around with in the spare time between one meeting and the next one.  It is a Scheme interpreter that includes a REPL window. The full code is here.

All the smarts for it come from this Wiki Book. I just ported the code to F# (and modified it a bit). I thought the comparison might be interesting, so here we go. Thanks to Tobias and Jose for reviewing the code, find one bug and suggest improvements.

Before we start looking at the real code, here is what we are trying to accomplish in form of test cases. If you are a bit rusty on LISP syntax, you might want to try and see if you understand what it does.

Our goal is to make all this XUnit…
