If you had seen my $MY_VAR would you be baffled because you had not seen $MY_VAR defined anywhere? ;-)

Anyway, it localizes the type glob MY_VAR. Before we had autovivifying refs to filehandles, "everyone" used plain filehandles instead of references to handles. This was (and is) a way to localize handles.
