I got decently far in my implementation, but probably wouldn't suggest you use this. The actual guide is pretty sloppily written and doesn't outline all that much, along with not explicitly saying what you have to define at each step. It doesn't define what the different cases of the mal Lisp value type should be, for example, or when to implement pretty much all of the "optional" extensions it mentions in the first or second chapter. Most of the forms in each chapter get a sentence explanation of what they do, at most, and I hit several snags where I read an explanation and thought I implemented it correctly, only to find out there was something subtly wrong with the obvious implementation. Also, writing a Lisp in a purely functional language isn't the best :X Things like by-reference function environments and atoms are hard to implement if you're not Haskell, at least if you try in the method that the guide outlines...
