Comment:

 refold: It's a good question, and thinking about this question more
 carefully, no, this patchset alone doesn't give us the capability. The
 problem is that GHC is still tightly coupled to ghc-pkg, but ghc-pkg still
 has a Cabal dependency and thus if you update Cabal, you also need to
 upgrade ghc-pkg. So, the only way to make Cabal separately upgradeable is
 by siphoning ghc-pkg off into a proper package, relaxing the tight
 coupling and upgrading it when you upgrade Cabal. duncan, can we do this?
