In my humble opinion, I think the problem is that the gettable and index
tag methods are on the global table, rather than on the global
variables. I think this makes globals distinct entities even more than
in lua 4.0. I think a nice solution would be to ADD two tag methods
"set" and "get" on variables. This methods would substitue the
getglobal/setglobal pair, because they would work on every variable for
which the TM is set (local or global, in a table or not).
