  * Make ResolvedPackage an instance of Package and PackageFixedDeps
  And use that to simplify the code slightly. Also add an assertion into
  removeFailed, that the first returned result is the failed package itself,
  since we'll rely on this in the install code.

    M ./Hackage/DepGraph.hs -11 +15
