[Haskell-cafe] Haskell data types and Storable class

Hello,

     I am reading the FFI spec. Something is unclear to me. Let's assume we
have

         data A = {b:B, .......}

    and

         data B ={ .............}

both of which belong to class Storable. In the A instance of Storable I want
to do a poke and peek of "b" into and out-of, respectively, B. How do I
write the poke and peek function of "b" in the "instance Storable A"?

thank you, Vasili
