I don't think this completely sane :-)
It's not fair or reasonable for the GHC project to require everyone else
contributing to the core libraries to validate their changes against
GHC. We need to be branching the shared repositories, so that we can
keep the GHC branches working and sync up with the shared repositories
as necessary. Morally this is the right thing; technically its a lot
more difficult than not forking.
What would make it much easier is for both the original shared
repository and GHC's branch to be git repositories (or branches of the
same repo): git is really good at having two parallel lines of
development that sync occasionally. Having one in darcs and one in git
would be painful, but doable.
So I suggest we propose moving all the core packages to git, and we
translate all those for which nobody objects to the change. For the
others, we'll keep them in darcs and live with the pain.
