this code is valid for luna template for lua 4.x (I think)

int your_class::check(lua_State *L)
{
	your_class *p;
	lua_pushnumber(L, 0); /* userdata object is stored in index 0 */
	lua_gettable(L, 1);		/* first argument for the user function y the table object
	p = (some_class *)lua_touserdata(L,-1);
	lua_pop(L,1);
	...
	... 
	...
}
