Could you add this info/link to the upgrading page?
http://www.haskell.org/haskellwiki/Upgrading_packages#Arrow_instances>,
Using social/community processes to parallelise the job of finding all the upgrade routes -- I like it :-)

Hi Wolfgang,
I use CPP to manage such differences between 6.8, 6.9, and 6.10. As an example, see [1] http://hackage.haskell.org/packages/archive/TypeCompose/latest/doc/html/src/... .
Regards, - Conal

Hello,
how do I make a library work with both GHC 6.8 and GHC 6.10? According to <[3] 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?
