how do I make a library work with both GHC 6.8 and GHC 6.10? According to http://www.haskell.org/haskellwiki/Upgrading_packages#Arrow_instances, I should change all my Arrow instances but then they don't work with GHC 6.8 anymore, do they? Or is the solution to force GHC 6.8 users to use base-4.0.0.0?
GHC 6.8 users can't use base-4. I think it's either two versions or cpp.
