Hello, I am trying to recompile some haskell code. I have previously compiled it with ghc 6.4 and that went fine. The lines that give the trouble are import qualified Data.Edison.Coll.UnbalancedSet as US import qualified Data.Edison.Coll.MinHeap as MH data DecoratedFormula = DF{formula :: Formula, iformula :: IFormula} type FastClause = MH.Min US.Set DecoratedFormula When compiling with ghc 6.6.1 and edison 1.2.1 I get the following error message: FastClause.hs:71:25: `US.Set' is not applied to enough type arguments Expected kind `*', but `US.Set' has kind `* -> *' In the type synonym declaration for `FastClause' I have no idea how to solve this error, since as far as I can see the type declarations of both MinHeap and Set do not seem to have changed. Any suggestions are more then welcome. Regards, Brammert
