I've modified Haddock so it can dump the interfaces it has parsed (I
simple made Interface an instance of Binary with some TH code). The
Interface contains the parsed Haskell code plus documentation and this
serves me well since I only intend to create tools like a graphical
browser, :doc in GHCi and @doc in lambdabot.
I've had some setbacks while hacking on the browser (named wxHaddock
in lack better) and the lambdabot module but I'll probably finish both
when I get some more time on my hands.
