Yes, plus the fact that you need some assembly to make all this work I guess.

For each C function you want to export to Lua, register a closure of the
universal wrapper with the actual C function (plus whatever information you
need to get arguments from the C stack and push them onto the Lua stack;
you'll need to know the number and types of arguments for this).
