brid.js (pronounced like "bridges")
is a LISP that uses JSON instead of S-Expressions
implemented in JavaScript

based upon Peter Norvig's lis.py
(Sorry I dropped your ai-class, Peter.)

This was partially inspired by Stuart Halloway's talks
"Simplicity Ain't Easy" and "Radical Simplicity"

But the real story is:
Sometimes I need to use JSON outside of REST
And I've started using a style of
JSON document that looks a lot like S-Expressions.
