Compatibility libraries

[Einar Karttunen]

Hello

In many invidual projects one is faced with challenges from the changing
standard library. Currently it seems that each project uses a separate 
solution - maybe a common approach would be possible. I would be most
interested in packaging a library which would implement GHC 6.4 
base package for older releases (mainly GHC 6.2.x).

GHC seems to have its own solution in fptools/ghc/lib/compat/ but 
having a cabal package and supporting e.g. Data.Map/Set could make 
things easier. Does this sound like a good idea or is there a much
better solution?
