Is it possible to know if LuaBridge called my code

[rpatters1]

I am trying to get robust error handling in place with code that may be in a callback from LuaBridge or may not. Is there any way to tell if LuaBridge called my code? That is, if LuaBridge is somewhere higher on the stack? Conceptually I would like to do this:

void error_handler(luabridge::LuaException &e)
{
   if (<called-by-LuaBridge>)
      throw e; // let LuaBridge and Lua error-handling handle it
   display_message_to_user(e.what());
   lua_close(e.state());
}

It looks like this works:

void error_handler(luabridge::LuaException &e)
{
   lua_Debug ar;
   if (lua_getstack(e.state(), 0, &ar))
      throw e; // let LuaBridge and Lua error-handling handle it
   display_message_to_user(e.what());
   lua_close(e.state());
}

If you agree, please feel free to close this issue. If there are improvements to suggest, I am interested in hearing them.
