Changes to GHC that will expose new packages

Could you explain what that API will look like? E.g., why does the
*library* need to depend on haskeline instead of just the executable?
I think a GHCi API should expose the commands of GHCi, but not the
command line interface of the ghci executable. At least that's what
my plans were for such an API (which would have been a package not
bundled with GHC).
I really don't like adding package dependencies to GHC because it now
means that package is tied to GHC's release schedule. (That is unless
the dependency is truly internal, but then why does the GHCi library
depend on them?)
If the new packages are really necessary then I'd prefer using the
(automated) renaming with the "ghc-" prefix.

Push the envelope. Watch it bend.
