Ha ha ha! Absolutely fantastic. The wizard would be proud! How do you handle tail call optimization with JavaScript? (at least, until the next version of JS with proper tail calls - woot! http://wiki.ecmascript.org/doku.php?id=harmony:proper_tail_c... )

Here's direct links to the source (which is worth looking at).

The definitions of all the caddr, cdadr variants is kind of fun, and the definition of "lookupVariableValue" is enlightening, if you were curious about how that sort of thing worked in Scheme.

If that's the case you should really read SICP, since there's a lot more enlightenment where that came from, so to speak.

Scheme in JS is an attractive idea, but it looks like the reader isn't doing reader-macros correctly:

    '(a b c)
    (Error: Unbound variable: "a" Error: Unbound variable: "b" Error: Unbound variable: "c")

There are a couple others of these:
