But in order for me to do what I need to do, it must be done in C -
otherwise I cannot do it between states!

// This is what I'm thinking - just as a guideline - This code is just
typed in netscape!
void CloneObject(lua_State *from,lua_State *to,lua_Object *Object)
{
  TObject *O = luaA_Address(Object);
  switch(ttype(O))
  {
    case LUA_T_NUMBER:
    case LUA_T_STRING:
    case LUA_T_NIL:
    case LUA_T_USERDATA:
      // are all easy enough! (I Think!)
      getglobal in state A
      push state B
      setglobal in state B
      break;
    case LUA_T_PROTO:
      // How do I clone a proto ??
      break;
    case LUA_T_ARRAY:
      // Loop Thru all elements in table and push in other state
      Create empty table in state B
      loop elements in table and push to new table in state B - if type
= array do recursive!
      setglobal table
      break;
    default:
      // Error !
      break;
  }
}

How to clone a proto ?
