Tonight I tried to use the module code to write an FFI module using
libffi. I found some holes that make this difficult to do.

It would be great to be able to make new types from C. That would let
me wrap up various C objects I'd like to return opaquely to Lisp.
Wrapping pointers would be good enough (for now I am using bit vectors)
but having more control would be much better.
Overkill here is better. You'll want to extend this vtable over time,
for example to add a GC mark function. I don't particularly care if the
vtable is exposed or private.
Of course, if you can add types from C, why not from Lisp? But I guess
I could write a module to allow that :)
Here's my list of other things that I noticed.
Note that my module isn't working yet, so take it with a grain of salt.
* I found the emacs_runtime / emacs_env split strange. I don't know
what the purpose of this is. Also there doesn't seem to be a way to
free an emacs_env, which I suppose makes sense in a way; though
shouldn't they simply be GC'd as well?
* module-call never frees "args".
* For error handling for now I ended up just calling Emacs stuff
directly.
