 #Overview
 
-## Algorithms for The Little Clojurer
+## Algorithms for The Little Schemer
 
 I was not fortunate enough (some would say unfortunate enough) to learn Lisp/Scheme in college.  It has been on my list for years and when Clojure came along and started getting popular, I decided it was time.
 
 Douglas Crockford says in _JavaScript: The Good Parts_ that all computer scientsts should read _The Little Schemer_ to truly understand recursion and how to think recursively.
 
 Not being content to do one thing at a time, I decided to combine this reading with learning the modern Lisp-on-the-JVM, Clojure.  So I read _The Little Schemer_ and every time it challenged you to write the algorithm, I did so in Clojure.
 
+About half way through, I started doing it in Scala as well, which I am also in the early stages of learning - trying to figure out how to do functional programming in Scala.
+
+
+### Clojure Notes
+
 This repo has all the algorithms in _The Little Schemer_ done in Clojure, using only Clojure's lists and the core methods of ISeq: <code>cons, first (car), rest (cdr), number?, list?</code> and in later chapters the built-in <code>=</code> method, since it is multi-purpose for multiple datatypes and, also in later chapters, the arithmetic operators.  Everything else was implemented from first principles according to the teachings of _The Little Schemer_.
 
 The algorithms are in the file **littleclj.clj**.  I also write simple assert tests for them in **littleclj-test.clj**.  At the time I wrote these I didn't know how to use Clojure's assert method nor any unit testing framework, so I wrote my own poor-man's version.
 
-I run all this code in the Clojure repl that came with Stuart Halloway's *Programming Clojure*.  So it was developed using Clojure 1.1.  **TODO: need to test with 1.2 and 1.3 - how get a REPL for those env's?**

 This was a great way to learn the subset of Clojure required to implement core Lisp/Scheme style functions.  I would like to do the same exercise in Scala, which I'm also in the middle of learning.
 
 Of course, there is a sequel to _The Little Schemer_ - _The Seasoned Schemer_.  Perhaps I will tackle that one as well?

-Currently, I have finished up through chapter 6.  More coming soon.
+### Scala Notes
+
+Doing this in Scala is harder because it is not a Lisp and has strong typing, so handling the typing has been interesting, but helping me grok Scala.  I don't claim this is at all idiomatic Scala.  Idiot Scala, maybe.
+
+For now I've implemented very simple assert functions after how I did it in Clojure.  I need to learn ScalaTest and port my tests to that...
+
+The single .scala file is meant to be run through the scala REPL, since Little Schemer functions and tests are all in this one file.
+
+## Status
+
+Currently, I have finished up through chapter 8 of with Clojure and in the middle of chapter 6 for Scala.  More coming soon.
