Is this true? I thought that ghc has separate machine code and byte-code modes, and inferred that the latter was platform-independent. Is the latter platform-specific because it is just a different way of organizing different ways of (unlinked) machine code, or because parts of the byte-code depend on things like the size of integers in the compilation machine that are platform-dependent? Also, it is worth noting that Clean supports serialization of values including closures. It's not entirely clear to me how they do this, but looks like some combination of seeing whether a referenced routine is already in the current executable, then seeing whether it is in a nearby library, and then finally just-in-type compiling the serialized platform-independent bytecode into native code.
