Many thanks, I will try.
In reverse order, I think it is not possible, MyItem is part of MyValue.
But I think of using it (MyItem) independently of MyValue, when this is possible.

lua_pushvalue, works, but only if disable that:
//luaL_getmetatable(L, MYITEM_REGISTRY);
//lua_setmetatable(L, -2);
lua_pushvalue(L, -2);
How to discover what MyValue position is?
Why does the register metatable MYITEM_REGISTRY confuse MYVALUE_REGISTRY?
