[Haskell-cafe] How to deal with dependency bounds for an application

Yes, looking at the last two haskell platforms might be a good pragmatical choice.

I even like the idea that much that I might add a feature to my own dependency
handling tool cabal-bounds[1]:

   cabal-bounds update --lower --haskel-platform=2012.4.0.0 ...


I think that getting the lower dependencies "right" is more an issue for
libraries, because in the case of applications a cabal sandbox can avoid
most of the possible problems.


Greetings,
Daniel
