That was Ashley's original proposal, but SimonM responded in http://www.haskell.org/pipermail/glasgow-haskell-users/2001-September/002290.html http://www.haskell.org/pipermail/glasgow-haskell-users/2001-September/002304.html that the extra boxing was unsafe in GHC. Hence the Finalizable class for boxed primitive objects, similar to the way UArray's are presented without exposing GHC's unboxed types. _______________________________________________ FFI mailing list [EMAIL PROTECTED] http://www.haskell.org/mailman/listinfo/ffi
