IMO, that is probably not a productive approach. The advantage of plugins
(slang) is that they are reliable and stable, and they let the C compiler
worry about low level things such as data structures and word alignment.
FFI interfaces are free of the requirement to compile one's own VM
plugins, but they are relatively fragile and dependent on low level
platform and compiler differences.

If you combine the two, you get the worst of both worlds - a relatively
fragile and platform-dependent interface that still requires you to
compile your own plugins.
