Entirely possible. Though it would be interesting to see the code that is to process the arbitrary types as they arrive, after deserialising. Anyway there was a thread on this last week. One solution is to have a symbol table mapping type reps to values of a given type, then you use that to know which type to read from the constructor tag, resolving the problem of not knowing what type you're reading. -- Don _______________________________________________ Haskell-Cafe mailing list [email protected] http://www.haskell.org/mailman/listinfo/haskell-cafe
