Can we define something like LOGICAL_REP_MSG_LAST (also add a comment indicating this is a fake message and must be the last one) as the last and just check that?
I don't think that's required once I applied suggestions from Kyotaro and Peter. Please check the latest patch.
Usually LAST is added to an enum when we need to cap the number of symbols or want to find the number of symbols. None of that is necessary here. Do you see any other use?
