Hello, We are adding classes and instances to Helium.
We wondered about the aspect that it is allowed to have a class instance of which not all fields have a piece of code/value associated with them, and that as a result when you happen to call these, a run-time error results. (see Sec. 4.3.2 of the Haskell 2010 report). Does anyone know of a rationale for this choice, since it seems rather unhaskell-like. best, Jur _______________________________________________ Haskell-prime mailing list Haskell-prime@haskell.org http://mail.haskell.org/cgi-bin/mailman/listinfo/haskell-prime
