"Remembering" data type contexts shouldn't break existing code, unless it's semantically broken already. (I'm sure that anyone could come up with a theoretical example of code which would break - but would it break any real-world code?) _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
