This is, in this case, incorrect. Unless I am horribly mistaken, the
higher cost of dealing with globals is that you first have to do a
failed lookup in the local dictionary. (Plus failed lookups are more
expensive than successful ones)
In this particular case the local dictionary is the same as the global
one, so I don't see how moving to a function would offer a time savings.
