vacuum allow that and much more though I don't know if it still works correctly on GHC 7.4. Anyway your isThunk is > isThunk a = fmap GHC.Vacuum.ClosureType.isThunk GHC.Vacuum.closureType (Feel free to arrange your imports to make that a bit more readable ;) http://hackage.haskell.org/package/vacuum -- Jedaï _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
