Great. To late ;(
I've now implemented this as well. My setup is getting the information
directly from the installed packages (thus ghc-pkg describe package and
then ghc -show-iface eachmodule.hi) Because I use caching it
should be reasonable fast ? (I hope so, I still have to do some testing)
The used packages are taken from the cabal file (and / or buffer
setting)

  import Foo (a)

add identifier b
results in
  import Foo (a,b) 

? 

or for the whole module it comes from (this feature

I'm using tags and the plain source file most of the time.
So I don't have trouble generating haddock documentation.
I think its easy but I haven't spent much time on this.
It contains all, the documentation and the implementation.

I'll let you know when having finished the quickfix integration.
Perhaps this can be done all automatically?

This might be useful, too

I don't know HaRe at all. Would this even work when working with #ifdef
etc?

I'd like to have some features, such as _T ..
But this only works if the file can be parsed by ghc, right?

Thanks for your suggestion.
