[Haskell-cafe] Haddock, wrapping contexts?

This is a bit silly and doesn't directly address the problem, but maybe 
you could re-package some of the Constraints into a type synonym? (I 
think you would need some extension like -XConstraintKinds for that)

Like this:

     type DefaultUnpack cols       = Default Unpackspec cols cols
     type DefaultNull   cols nCols = Default NullMaker  cols nCols

     leftJoin :: (DefaultUnpack columnsA, DefaultUnpack columnsB, DefaultNull columnsB nullableColumnsB)	
              => [..]
