I like JSON for pulling data out of web apis, combined with the parser
it becomes very convenient.

There is one in contrib, I've used it a bit and it is quite good.

Yeah, I made my own ad-hoc transactional caching thing, and it was
quite nice being able to simply print stuff out line by line and then
read it in with { } wrapped around it.
The code is similar to the code for memoise, just with an extra step
of writing stuff to file and reading it in at a certain time.
(interestingly means you can disk cache any fn that is referentially
transparent and returns a clojure structure).
