Hmm, do you know that Haddock can already generate a Hoogle database?
If so, is this database significantly different?
About the dependency, I don't think we can depend on syb as it's not a
GHC boot library. (Haddock is used in the GHC build process and can
only depend on boot libraries). syb was moved out of the boot
libraries a while ago, unfortunately.
Thanks for the patch, I will take a look at it.
