Any opionions?
I think we need to decide how the further development of the FFI will proceed. Given that Version 1.0 of the Addendum is frozen, I am not in favour of changing the Addendum anytime soon and certainly not for small matters, such as a convenience function. We might want to accumulate extra useful functions in the implementation in an *extra* module and once there is enough interesting functionality in there, we can start talking about Version 1.1 of the Addendum. Does this sound like a sensible approach? Manuel _______________________________________________ FFI mailing list [EMAIL PROTECTED] http://www.haskell.org/mailman/listinfo/ffi
