ron has a hacked 8c with support for dynamic loading, he did it for
python.  I recently did an APE port of python with the standard 8c.

if I need/want a new module I just rebuild it, I have
/$objtype/lib/ape/libpython.a and a special mkfile in a Extra/ 
where I just put .c files in a dir per module, the mkfiles are smart enough
to build everything and add the init fn() calls to some initmodule()
maybe it's a bit overkill, but who knows...
