Hi Matt,

thanks a lot for the detailed writeup of your experiences, that was a
very interesting read! Being pretty much oblivious with regards to Jinja
I will only comment on one issue:

This doesn't seem like a very good idea to me. You might generate
invalid JSON if the values you pass into the template don't happen to
have textual representations which also happen to be valid JSON values
(if I understand the way Jinja works correctly here). I'd suggest using
a proper JSON emitter like the one contained in medea
(http://wiki.call-cc.org/eggref/4/medea) instead.
