Instead of letting the compiler guessing a portable name, I'd rather
give explicit names to code pointers. Like Callback.register in the FFI.
You'd also get the possibility to maintain ABI stability.

I'm not convinced this is better. I don't think having the possibility
to serialize /any/ closure is a good thing. IMHO, serialized functions
are like exported functions in modules. Their stability should be
guaranteeable at ABI level, which is not something you want for everything!
