How about defining an attribute that is the name of the js variable
for use with that element? Then you can define the variable in a
<script> tag, and use pure JSON cleanly.

Kristof, JSON is in fact pretty much valid Python syntax too. It is a
Javascript subset for decalarative structures designed to interoperate
with many languages.
