Those restrictions should fit my case very well.  I have a .cabal file, I'm
mainly interested in functions, and it's just an executable not a library.

I don't think that will be a problem.  I still haven't upgraded to 6.10 due
to it uninstalling 6.8 (has anyone fixed this on osx yet?).  And we don't
use view patterns so HSE-4 is hopefully not needed.
