+I've been working my way through a Lisp textbook, *Lisp In Small
+Pieces*, by Christian Quinnec.  It was originally written in French and
+is not that well known among English-speaking Lisperati, not in
+comparison to the Wizard book or Paul Graham's *On Lisp*, but what
+caught my attention was how it really was in *small* pieces.  Each
+chapter ended with an interpreter described, sometimes in code,
+sometimes in text; if you were smart enough, you could actually piece
+the whole thing together and see how it worked.
+
+I decided to make things hard for myself.  Since I'm *not* a Lisperati
+(although I may well and truly be seduced by Hy), I decided to make
+things hard for myself by writing the interpreter in Coffeescript.  Most
+Lisp books assume you have a Lisp handy, and Quinnec's examples are fine
+and dandy on many variants of Scheme, but for a fun time I decided to
+write it in something else.  Raganwald claims Javascript "is a Lisp,"
+and if that's so it ought to be good enough to write a Lisp in it.
+
+I mean, it's obviously been done before.  I tried once before but got
+lost.  *LiSP* does me the favor of keeping me on track.
+
+You can see all my sourcecode at <a
+href="https://github.com/elfsternberg/LispInSmallPieces">Github: Lisp In
+Small Pieces</a>.
+
+Chapter 1 contains the base interpreter.  It also contains a
+hand-written Lisp reader, and refers to another project I have on
+GitHub, <a
+href="https://github.com/elfsternberg/cons-lists">cons-lists</a>, which
+is exactly what it sounds like, a singly-linked list implementation in
+Javascript, using nested Javascript arrays as the base.  The base
+interpreter is very primitive-- you can't even create new variable names
+in the global namespace!  Although you can shadow them using lambdas, so
+it's pretty much bog standard Lambda Calculus.
+
+Chapter "Lambda 1" contains a continuation-passing variant of the
+interpreter from Chapter 1.  It's basically a facile reading of
+Lisperator's λ-language intepreter, with my own parser front-end and
+some CPS style.  It passes all the tests, but it's a distraction.
+
+Chapter 3 contains the same interpreter, only using the architecture
+Quinnec describes in Chapter 3 of his book.
+
+Chapter 2 describes a number of different methodologies for binding,
+scoping, and namespaces.  The material is interesting but I didn't
+pursue writing the various interpreters.  I "got" what Quinnec was
+saying, and if I'm ever interested in writing something with scoping
+rules outside of the lexical scopes with which I'm familiar, I might
+revisit the material.
+
+The next step will be to add functions to the Chapter 3 interpreter to
+do the various continuation management games, like call/cc, throw/catch,
+and so forth.  Because *those*, I feel I need to understand.
