You have the impression I plan to stop working with/on arc, which is not the case.
The whole point of the FFI is to interface with other languages and such... so I would then need to know the other languages to make further use of the FFI.
I don't know why I would want to write a packaging system, but assuming we're referring to the same kind of packaging... I probably wouldn't use arc when many well developed solutions in other languages already exist.
