Not sure that's helpful to you since it's a C binding solution, but i haven't 
found anything that i could use related to JSON in Haskell since i wanted:

- event based parsing.
- DoS protection.
- integer and float represented as array of bytes.
- and last but not least break neck speed.

so i ended up binding my own C embedded library [1]. I could clean up my ugly 
bindings and publish it somewhere if it's useful.
I do have a plan, someday, to experiment with a rewrite in haskell using the 
exact same technique but the will and time to do so have lacked so far.
