Simpler, yes.  Not necessarily faster, and I was surprised when I
actually measured iteration on .keys vs iteration on .items: the
allocation/building of the N pairs may apparently take longer
than the N [] indexing operations.  Measure the two alternatives
if you do need top speed at this point...
