Right, I was aware that nhc98 uses this method but forgot to mention it. 
Thanks for pointing it out.

I think it makes a lot more sense for us to re-use parts of Cabal than to 
re-implement the whole thing, although the balance is probably different 
for nhc98.  Cabal generates the InstalledPackageInfo from the .cabal file, 
for example, and this is certainly something we don't want to re-implement.
