Well, the need for extracting the underlying char pointer to call the c function does limit possible abstraction of the data structure somewhat. Of course, one could make a type class providing unpack/pack functions for extracting the pointer and rebuilting the Haskell value. Of course, this was never meant as part as anything, but a low level crypto lib for high level crypto libs to use. It's not meant for regular usage. -- Johan Brinch _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
