tnx now I understand how __index work,but in wich way I can do this in c++?
I can do a chain of metatable(in some way) or I must write a function that 
retrive the father metatable and search for methods?
I am working on luna template that i find in the wiki that set __index whit 
the methodtable
...
lua_pushliteral(L, "__index");
lua_pushvalue(L, methodtable);
lua_settable(L, metatable);
...
Can I set for example __index of the methodtable whit the methodtable of 
the father?

Sorry for my English.
