I've actually thought of a nice way for library builders to make libraries
more user friendly.  (Not sure how original this is, but I have never seen
it doen, it seems quite obvious to me).

Say you have a mydll.dll with a c_func in it called mycfunc that takes two
parameters of C_INT and returns a C_INT.

mydll = open_dll("mydll.dll")
cfunc1 = define_c_func(mydll, "mycfunc", {C_INT, C_INT}, C_INT}
global function mycfunc(integer first, integer second)
    return c_func(cfunc1 , {first, second})
end function

We can now call mycfunc as if it was just a regular function.  No more user
playing around with c_func and c_proc.  Just an idea.
