JSON is in fact a subset of JavaScript, and modern browsers now
include a specific API for parsing and generating it
(https://developer.mozilla.org/En/Using_native_JSON ).
Python likewise has a JSON module in the std lib:
http://docs.python.org/library/json.html

The word "array" gets tossed around a lot by programmers. The `array`
module is not at all what you want in this case.
