It seems to compile and parse JSON fine with attoparsec 0.9.1.2.
The cabal file restriction to attoparsec 0.8 is preventing me from upgrading some other things that depend on attoparsec 0.9
Should be all set with JSONb-1.0.5 (commit 429573c).
But umm, the attoparsec upper limit is still in place in "executable" section on line 53.
Okay, sorry. My system has both old and new Attoparsec installed. It really works this time! (commit 5085f8e)
