lua_Object is dead. Good riddance!

The vibe I get from the tolua documentation it that is really all
about exporting *existing* C interfaces (which make no mention of lua
because they were not designed with lua in mind) rather than designed
a specific lua/C interface. So it makes no allowances for
Some ways which you could do this:
Pass a string which is the name of a global variable which is the
Pass a string or number which an index into some 'callback table'
which your application uses to store callbacks.
Bypass tolua and interface this function by hand.
