Oh, I see: you use 'with' as a heuristic for guessing the motive of the inductive family elim. How do you pick which occurrences of the with-scrutinee to refine, and which to leave as a reference to the original variable? You don't always want to refine all of them, do you? -Dan _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
