You can build Lua as C library and use lua_pcall.
So you create C function which did not have any C++ object in stack.
This function interact with Lua API.
And you can call this function from C++ function using lua_pcall.
You can pass any C++ objects as pointer via upvalues.
Of course you have chance get error on lua_push***. But I just ignore
this.
