Who is willing to write applications that are unsound?
Once Ocaml generates -fPIC it can be linked with a C wrapper
to make a shared library, and your mainline (or another
wrapped library) can embed a function that loads such
libraries with dlopen() and retrieves a record of functions,
then casts it to the expected type ..
voila, you have native code plugins.
Note even bytecode cannot *unload* plugins .. which is
needed to execute user scripts in web pages with
long running server side scripting support.
